There are no dependences on the development of any primarily or secondary bonds between the components materials. force). (e) Contribution Margin Method: This method employs marginal costing technique for apportioning joint costs among the joint products. The larger the area you … Bearing force is imposed by this type of fastener hole and plastic deformation of the material surrounding the hole on opposing structure elements. The low force is then compared the force to cause slip because to earlier for an assumed value of average fastener joint preload. Mechanical joining is to attachment of components in an assembly to use of either an integral feature is used the part to install the supplemental device called a fastener resulting in integral mechanical attachment and mechanical fastening, respectively. (T) FAB= 500 lb. Friction joint also the intent to have an appropriate fastener, for example a bolt or machine screw or, sand rivet to apply a clamping load high enough to cause sufficient frictional force to applied the load, The fastener is protect from ever having to carry shear or cause bearing. And no atomic —level bonding are created and no chemical interaction. Wood Joints Advantages and Disadvantages. They are used to span greater distances and to carry larger loads than can be done effectively by a single beam or column. Here are the advantages of Riveted joints when compared to welded joints. One even needs to worry about water infiltration in such joints, since water acts as a lubricant and drastically lowers the slip coefficient of a joint consider being dry during operational service. • Welding process is quicker as it requires no drilling of holes. The joining can loosen in service as a result of vibration. The shear stress produced in a fastener given load depend on the actual cross sectional area of the fastener, and this is affected by whether the fastener is threaded and unthreaded in the region through which a shear plane in the joint elements passes. Values can be seen to be highly dependent on the treatment and condition of the joint surfaces, which must be carefully stipulated and controlled for such friction-type joints to work reliably. When these joints are operating properly, the frictional force developed precludes the fastener from having to carry and apply a bearing force by not allowing slip of the joint elements. force), b is the number of shear planes that actually pass through the unthreaded fastener or portion of the shank of a fastener. The third disadvantages of mechanical joining can be the open nature of the joint between points of fastening, around fasteners and between points of attachment. The second advantages is uniquely allows intentional disassembly without damaging parts involved. Some of the probems associated with joints are treated consevatively, but some conditions needs to be treated surgically. Wood joinery is an ancient craft that marries pieces of wood, allowing for the construction of furniture, cabinetry, flooring and framing. Trusses: Method of Joints Frame 18-1 *Introduction A truss is a structure composed of several members joined at their ends so as to form a rigid body. It is an important fabrication process. What Are Some Advantages & Disadvantages of Stretching?. Profit at low cost: A joint venture created to complete a certain task or project. Joints demand careful design for all forms of joining, including mechanical fastening or integral attachment. Consequently they are of great In friction shear loaded joints, the fasteners must create a significant amount of clamping force on the joint, holding the joint elements together and prevent any motion and slip. For example of fastener requiring hole is screw, key, bolt, rivet and pin. 1st Jan 1970 This procedure can be more fasteners are assumed to carry on equal share of the applied force and load. As stated earlier, most joint are critical element of assembly and structure. There are no dependences on the development of any primarily or secondary atomic, ionic, or molecular bonds between the components materials. We will see here, in this post, the analysis of the forces in the various members of the truss by using the method of joints. For other type is virtually all integral attachment, stress concentrates at the point of attachment. By using the welding process, changes can be made. Stress concentration is particular concern in fatigue critical structure, but it can more aggravate accelerate corrosion. If the interaction occurs it is usually seen as problematic such as galvanic corrosion or galling and seizing during adhesive wear. This popular type of metal connection has many advantages over traditional joints, ranging from its speed to its strength, visual appeal and more. The method of joints analyzes the force in each member of a truss by breaking the truss down and calculating the forces at each individual joint. The sixth advantage is provides a simple of achieving of structural damage tolerance beyond inherent material damage tolerance. It works by cutting through the whole truss at a single section and using global equilibrium (3 equations in 2D) to solve for the unknown axial forces in the members that cross the cut section. Any opinions, findings, conclusions or recommendations expressed in this material are those of the authors and do not necessarily reflect the views of UKEssays.com. For many years, it was accepted as part of warming up for a workout. Empirical used to determine the maximum working stress that can be allowed in the fastener. Advantages and Disadvantages of Welded Joints over Riveted Joints . Bearing force is imposed by this type of fastener hole and plastic deformation of the material surrounding the hole on opposing structure elements. This procedure allows the designer to choose the low joining in the structure. Mechanical joining offers many advantages compare to other fundamental joining process. We've received widespread press coverage since 2003, Your UKEssays purchase is secure and we're rated 4.4/5 on reviews.co.uk. This procedure is generally accepted and is perfectly safe when conservative allowable are used, such as the result of imprecise analysis. A person welding. Stress also created by the fastener. Method of joints will find the forces in ALL members, and you have to start at a joint and continuously work your way around the truss to calculate forces in each member. Reference this. There are no dependences on the development of any primarily or secondary atomic, ionic, or molecular bonds between the components materials. There has two type of this process such as mechanical fastening and integral mechanical attachment, or simply integral attachment. Advantages of Bolted Connections. The low force is then compared the force to cause slip because to earlier for an assumed value of average fastener joint preload. The detailed methods by which mechanical joining is accomplished have expanded, the number of joints produced continues to grow, and the performance demands and expectations are becoming greater. The joint element is held together by shear in the fastener and the bearing force or stress in the joint elements created by the fastener. The forces from interacting structures, internal inertial forces, vibrations, and transients especially from startup, shutdown, and the temperature can be changes in thermal excursions, fluid pressures, prime movers. The sections are obtained by cutting through some of the members of the truss to expose the force inside the members. Shared loading also depend on all fastener being same size and material. The loads also can be static, for example for steady or unchanging and dynamic in combination. Using a welded connection, you're guaranteed of a 100% efficiency which is quite high compared to the 75 - 90% common with riveted joints 2. The method of joints is a process used to solve for the unknown forces acting on members of a truss.The method centers on the joints or connection points between the members, and it is usually the fastest and easiest way to solve for all the unknown forces in a truss structure. The necessary slip resistances, as the frictional force to apply in this way is called, depend on greatly of the surface conditions of the structural joint element materials at their joint faying interface. There are no dependences on the development of any primarily or secondary bonds between the components materials. No bonds need to be formed to accomplish joining, nor do any need to be broken to accomplish disassembly. For example of fastener properly used for bearing-type shear-loaded joints are nails, rivets, pins, and key. Mechanical joining offers many advantages compare to other fundamental joining process. Consequently they are of great ADVANTAGES AND DISADVANTAGES OF WELDED JOINTS . No plagiarism, guaranteed!

If the interaction occurs when seen as problematic such as galvanic corrosion or galling and seizing during adhesive wear. Mechanical allows components fabricated from different materials to be joined, since there is no need for chemical or physical interaction. They can be weakest link in some assemblies or structures, thereby being the most likely areas of an assembly or structure to damage or low joining parts. The third advantage is no bonds formed. In this technique, sections of wood get lined up. The sources of loads can be weight or force, example from snow, water, wind, or other parts of the structure. METHOD OF POINTING: All the mortar joints in the masonry are raked out to a depth of 10-15mm with the help of pointings tool. This procedure also is only truly valid for joint that are composed of perfectly material, which is not real case and at least valid for joint containing multiple row of fasteners. Mechanical joining is used to create assemblies or structures from detailed parts or structural elements.Mechanical joining has been critical to engineering such as in manufacturing, structure, and also in construction. In fact, tear out cannot occur if there are multiple rows of fasteners, given sharing of load by all fasteners. * First of all I would like to point out that method of joints is itself a subset of method of sections so basically we are doing it unknowingly all the time . Recall that only two equilibrium equations can be written 6.4 THE METHOD OF SECTIONS In the method of sections, a truss is divided into two parts by This popular type of metal connection has many advantages over traditional joints, ranging from its speed to its strength, visual appeal and more. Learn how to solve trusses using method of joints in this truss analysis example problem. There are no reports on the advantages of this method. No bonds need to be formed to accomplish joining, nor do any need to be broken to accomplish disassembly. The black bolts offer the following advantages over riveted or welded connections: Use of unskilled labour and simple tools; ... are prevented from loosening and the fatigue strength of the joint will be greater and better than welded and riveted joints. * So why do we use method sections? The most important aspects of the design of all joints is identifying the sources and estimating the magnitudes and directions of applied and internally generated loads. Shared loading also has fitting with equal tightness in fastener hole. The most important aspects of the design of all joints is identifying the sources and estimating the magnitudes and directions of applied and internally generated loads. This procedure also is only truly valid for joint that are composed of perfectly material, which is not real case and at least valid for joint containing multiple row of fasteners. Advantages of welded joints. Large bonded areas give strong joints with clean appearance but processing may be Complicated with some while edge preparation may be costly for some others. If the interaction occurs it is usually seen as problematic such as galvanic corrosion or galling and seizing during adhesive wear. Mechanical joining is used to create assemblies or structures from detailed parts or structural elements. So structural members are more effective in taking the load. The result can be fastener pull through or pull out. If the interaction occurs when seen as problematic such as galvanic corrosion or galling and seizing during adhesive wear. Because of the mechanical fastener is a stress and develop a stress concentration in the joint element. Where, is the most form of mechanical fastening and some form of integral attachment permit relative intentional motion between joined parts. This method has the advantage of measuring the efficiency and exercising control in producing joint products. Proponents … The joining can loosen in service as a result of vibration. Under the stress design procedure for bearing type shear loaded joints, the various elements of the joint such as including structural members and fasteners and must be sized so that the following conditions are satisfied, the fasteners can be not damage in shear by overload, the joint plate can be not damage in tension by overload, the fastener holes cannot be deformed by bearing loads from the fasteners, and the fasteners will not tear out of the joint plates at edges. The forces from interacting structures, internal inertial forces, vibrations, transients, especially from startups, shutdowns, and faults, temperature changes or thermal excursions, fluid pressures, prime movers. Advantages of Joint stock company in terms of capital, liability, Perpetual succession, Transferability of shares, Risk bearing capacity, economies of scale, Economic development, public confidence, Social benefits are briefly explained. There can also be a weight when compare to integrally attached as welding, brazing and soldering. You can view samples of our professional work here. Empirical used to determine the maximum working stress that can be allowed in the fastener. Starting a joint venture provides the opportunity to gain new insights and expertise. Stretching has certain benefits, but it also has its detractors.

To overcome the difficulty, another method is used often: Method of Sections. Other disadvantage of mechanical fastening is more intensity for assembly can be high, especially for high performance system. Mechanical joining is very important because the result more fastener from other process. The principle behind this method is that all forces acting on a joint must add to zero. It also can experience loosening and disassembly from flexing especially during impact from dropping, or material stress relaxation. Welded joints are more … *You can also browse our support articles here >. The method of joints is a way to find unknown forces in a truss structure. As stated earlier, most joint are critical element of assembly and structure. Mechanical joining has more advantages. Since only two equations are involved, only two unknowns can be solved for at a time. Disclaimer: This work has been submitted by a university student. It involves a progression through each of the joints of the truss in turn, each time using equilibrium at a single joint to find the unknown axial forces in the members connected to that joint. Where, mechanical joining methods or technique uniquely allow simple practical disassembly without damaging the parts involved. Rivet can be used in joining of ferrous as well as a nonferrous metal like aluminium and copper alloys. The advantage of the allowable stress design procedure is not precludes failure under any conditions such as although it does so under normal operating condition, but that it allows the designer to choose the mode by which the structure would ultimately damage. The joining process can remain the prolific, pervasive, and important of joining process. The resulting friction created between the joint and the result of their coefficient of friction and applied normal force. Advantages. The method of sections is an alternative to the method of joints for finding the internal axial forces in truss members. Mechanical joining is very important because the result more fastener from other process. Mechanical joining is used to create assemblies or structures from detailed parts or structural elements.Mechanical joining has been critical to engineering such as in manufacturing, structure, and also in construction. Looking for a flexible role? Is there another method to determine these forces directly? From the above information finally, we can conclude that why these joints are necessary for various applications. Mechanical joining, load are transferred from one component or element to another strictly through the development of purely mechanical forces rising from the interlocking and resulting interferences or vice versa of two or more components or components and fasteners. Mechanical joining is allows parts to assembly to move relative to one another to provide needed system functionality, while maintaining part arrangement, proximity, and orientation. The primary advantage of a tongue and groove joint is its stability. For your complicated structures, you'll find it easier to adopt welded connection especially in cases of steel pipes. The examples of fasteners properly used for bearing type shear loaded joints such as nails, rivets, pins, and keys . Welded joints are more economical as less labor […] Under the stress design procedure for bearing type shear loaded joints, the various elements of the joint such as including structural members and fasteners and must be sized so that the following conditions are satisfied, the fasteners can be not damage in shear by overload, the joint plate can be not damage in tension by overload, the fastener holes cannot be deformed by bearing loads from the fasteners, and the fasteners will not tear out of the joint plates at edges. Mechanical joining is allows parts to assembly to move relative to one another to provide needed system functionality, while maintaining part arrangement, proximity, and orientation. The sources of loads can be weights or forces as from snow, water, wind, or other parts of the structure. The utility of mechanical joining can be limited by materials anisotropy, particularly if that anisotropy leads to weakness through the fastening thickness, as in most laminated composites. Such joints can only be employed with materials that exhibit plastic deformation, yet still retain their strength or mechanical integrity. This procedure allows the designer to choose the low joining in the structure. Mechanical is the components to fabricated from different materials to be joint, There is no has for chemical and physical interaction. Study for free with our range of university lectures! The advantages of single-laps are ease of assembly and cost, and the advantages of double laps are elimination of eccentric loading and reduction of shear stresses at each of the multiple shear planes in the fastener in bearing type joints. In this illustrative example there are multiple rows of fasteners, so tear out could not occur and the holes on the second and third rows from the edge would have to elongate in bearing by enough to cause tear out of slugs between the first row and the edge. No lubricants can ever be used if not planned for at the design stage. Mechanical allows components fabricated from different materials to be joined, since there is no need for chemical or physical interaction. Riveted joints usually come with at least 75% of the sturdiness connection. The shear stress in bearing type connections is related to the arrangement of the pieces or structural elements comprising the joint. The bearing force also tear and slugs of material from the join element. Method of Joints. Rivet can be used in joining of ferrous as well as a nonferrous metal like aluminium and copper alloys. These various modes of potential failure are shown schematically. The advantages of single-laps are ease of assembly and cost, and the advantages of double laps are elimination of eccentric loading and reduction of shear stresses at each of the multiple shear planes in the fastener in bearing type joints. Welding method is a quicker way of connecting metal. The joints and the surface are washed with clean water and kept wet for sometimes. FBC FAC= 500 lb. Expansion joints are considered as very important components of a complete pipe system and are widely used particularly in industries where thermal expansion in pipe systems occur.. As pipeline expansion joints are designed to safely absorb the dimensional changes of steel pipe systems and ducts. You can easily create secure joints at home which provides the neat finish. Problem 001-mj | Method of Joints. Under this method the total joint cost is divided into two categories viz., variable … A method of producing ball joints of the type that include a ball and stem member pivotally mounted in a housing, the method comprising forming separate stem portions and ball portions and joining the portions at welded junctions with frictionally impored heat to provide pivot members of composite construction. Though there exist numerous types of wood joinery methods, in this article, you shall get insight into the advantages and disadvantages of the dowel joints. The welded structures are usually lighter than riveted structures. Advantages . The bearing force also tear and slugs of material from the join element. In the Method of Joints, we are dealing with static equilibrium at a point. There can also be a weight when compare to integrally attached as welding, brazing and soldering. Advantages And Disadvantages Of Mechanical Joining Engineering Essay. None of these modes will occur if the appropriate allowable stresses are not exceeded in the fastener, for example shear. There has two type of this process such as mechanical fastening and integral mechanical attachment, or simply integral attachment. The process causes no chemical and microstructure will be changes in the material being joined, so dissimilar types can be combine easily, and all can be intentionally disassembled to allow maintenance, service, repair, upgrade, ultimate disposal, or portability The joining parts assemblies and a structure element is joining in structures mechanical joining, which involves two major subclasses of mechanical fastening and integral in mechanical attachment. Above shown are the conditions of compression or tension, deceided as per the direction of force applied by the pin joints to the members. This procedure is generally accepted and is perfectly safe when conservative allowable are used, such as the result of imprecise analysis. In welding filler plates, gusseted plates, connecting angles etc, are not used, which leads to reduced overall weight of the structure. The second disadvantages of mechanical joining is mechanical joining related to above mentioned stress concentration is that the utility of mechanical joining. This process can be tedious when you need to find forces in only one member. Welding joints come in two major types and can be used for a variety of purposes. Mechanical fastener also relative to one another help distribute loading and also to edge of the joint elements. In a joint account, it’s easier to access the funds when the spouse passes away. For example, surfaces cannot be painted unless painting is called for and an approved paint is used. More recently, researchers have come to mixed conclusions. Values can be seen to be highly dependent on the treatment and condition of the joint surfaces, which must be carefully stipulated and controlled for such friction-type joints to work reliably. Where, this is very frequently essential for the purpose of portability, maintenance, services replacements, of damages parts, modification, of the assembly or structures. Ductile metals and thermoplastic polymers are the two example such as formed in folded tabs, crimps, hems, and punched stakes are good example in metals, and crimps, hems, and punched or heat set stakes are example in thermoplastic polymers. Advantages of the method of joints: simple, no moments considered. Now, we will be interested here to understand how to solve truss problems using method of joints step by step with the help of this post. Methods of strengthening the comer joints are shown in Fig. The black bolts offer the following advantages over riveted or welded connections: Use of unskilled labour and simple tools; ... are prevented from loosening and the fatigue strength of the joint will be greater and better than welded and riveted joints. No lubricants can ever be used if not planned for at the design stage. Machine Design Manufacturing Technology. The third advantage is no bonds formed. (e) Contribution Margin Method: This method employs marginal costing technique for apportioning joint costs among the joint products. A … If the interaction occurs when seen as problematic such as galvanic corrosion or galling and seizing during adhesive wear. The utility of mechanical joining can be limited by materials anisotropy, particularly if that anisotropy leads to weakness through the fastening thickness, as in most laminated composites. Mechanical joining is used joining or install structure from details parts and structural elements. Regardless of what action you’re performing whether it’s Welding, Brazing , Riveting, Coupling, Adhesive Bonding, etc (which we’ll talk about below a bit). The detailed methods by which mechanical joining is accomplished have expanded, the number of joints produced continues to grow, and the performance demands and expectations are becoming greater. The hole can create the stress concentration unless the fastener is interference is specially process to create a compressive residual stress to offset tension stress. The problem is to determine the various stresses produced in the fastener and in the joint plates by a load of 300kN (67,000 lbs. For example of fastener properly used for bearing-type shear-loaded joints are nails, rivets, pins, and key. 2 Finite Element Method The FE method is a numerical analysis procedure that provides an approximate solution to problems in various fields of engineering. 1.Method of joints. It is more reliable; It can also be used for non … The forces from interacting structures, internal inertial forces, vibrations, and transients especially from startup, shutdown, and the temperature can be changes in thermal excursions, fluid pressures, prime movers. For the both manifestations of mechanical joining, load are transferred from one component and also the element to another the development of purely mechanical forces and rising from the interlocking, and result can more components and fasteners. Dust and loose mortar are thoroughly cleaned. Joint bank accounts have their advantages and disadvantages. Stress concentration can lead to fastener hole or attachment feature distortion and loss of effectiveness. Mechanical joining is a load to transfer from one parts or element to another strictly and the development of purely mechanical forces arising from the interlocking and resulting interference of two or more components, or component and fastener. Mechanical joining also has disadvantages such as, all mechanical joining fastening and integral attachment is that stress concentrates at the point of fastening or attachment. Mechanical joining is used joining or install structure from details parts and structural elements. And no atomic —level bonding are created and no chemical interaction. A joint or articulation (or articular surface) is the connection made between bones in the body which link the skeletal system into a functional whole. Rivet can be used in joining of nonmetallic material like wood, plastic, asbestos sheet etc. A welded joint can provide equal strength as the parts of joint had been originally assembled as one united piece. While woodworking, dowel joints are considered the most reliable type of joint. Ductile metals and thermoplastic polymers are the two example such as formed in folded tabs, crimps, hems, and punched stakes are good example in metals, and crimps, hems, and punched or heat set stakes are example in thermoplastic polymers. Most cost or other process can be higher for some integral attachment method. Below are some of the advantages and disadvantages of each method. 5. Mechanical joining involves the attachments of components in an assembly or elements in structure through the either an integral of the components or elements or use of the supplement device called a fastener, which resulting in integral mechanical attachment and mechanical fastening. The lower of these determines the ultimate load-carrying capacity of the friction-type joint. the number of members is less than the required members.So there will be chance to fail the structure.. The loads also can be static, for example for steady or unchanging and dynamic in combination. The method of joints is a procedure for finding the internal axial forces in the members of a truss. Typical slip coefficients of friction can be found. The resulting friction created between the joint and the result of their coefficient of friction and applied normal force. The production of the rivet is cheap. Expansion joints are considered as very important components of a complete pipe system and are widely used particularly in industries where thermal expansion in pipe systems occur.. As pipeline expansion joints are designed to safely absorb the dimensional changes of steel pipe systems and ducts. Such as joint allows moisture, water, air, fluid intrusion, permits leaks, and can accelerate corrosion in the oxygen starved crevice and dissimilar electrochemical nature of the joined materials or any residual stresses. Mechanical joining is used to create assemblies or structures from detailed parts or structural elements. The shear stress in bearing type connections is related to the arrangement of the pieces or structural elements comprising the joint. Stress also created by the fastener. Joints demand careful design for all forms of joining, including mechanical fastening or integral attachment. The necessary slip resistances, as the frictional force to apply in this way is called, depend on greatly of the surface conditions of the structural joint element materials at their joint faying interface. Shear loaded types of joints and fasteners being described here, and for tension loaded types of joints and fasteners to be described in the next subsection. Flat surfaces receive strong support because it offers three strength layers where it joins. One even needs to worry about water infiltration in such joints, since water acts as a lubricant and drastically lowers the slip coefficient of a joint consider being dry during operational service. Such joints can only be employed with materials that exhibit plastic deformation, yet still retain their strength or mechanical integrity. From simple essay plans, through to full dissertations, you can guarantee we have a service perfectly matched to your needs. No matter what equipment is used, a welded joint is a crucial part of modern construction. Where, this is very frequently essential for the purpose of portability, maintenance, services replacements, of damages parts, modification, of the assembly or structures. Where, this is because the forces needed to hold the joint components together. The lower of these determines the ultimate load-carrying capacity of the friction-type joint. Method of joints. If there were three bolts in a row, there would be six shear planes such as on areas to cause tear out. The double-lap shear is composed of ASTM A36 steel, contain five 22 diameter ASTM A325 steel bolts arranged as shown although the specific pattern does not matter for symmetrical loading, the bolts have a thread pitch of 2mm per thread or, in the Unified system. Advantages / Disadvantages Of MoJ. No matter what equipment is used, a welded joint is a crucial part of modern construction. Welding joints come in two major types and can be used for a variety of purposes. Mechanical joining is the part method to joint components together, which mechanical joining is accomplished have expanded, the number of joints produced continuous to grow and the performance demands and expectations are becoming greater. Mechanical joining is a load to transfer from one parts or element to another strictly and the development of purely mechanical forces arising from the interlocking and resulting interference of two or more components, or component and fastener. Mechanical is the components to fabricated from different materials to be joint, There is no has for chemical and physical interaction. For friction joint, the design analysis is slightly different than for bearing type joint. Therefore, joints demand careful design for all forms of joining, including mechanical fastening and integral attachment. Method of Sections In this method, we will cut the truss into two sections by passing a cutting plane through the members whose internal forces we wish to determine. This can occur under static loading and the situation can be even worse for dynamic loading by impact fatigue. It works under the assumption that all the members are pin-connected, making them two force members. The result can be fastener pull through or pull out. force), b is the number of shear planes that actually pass through the unthreaded fastener or portion of the shank of a fastener. The following is a list of the pros and cons of having joint accounts: Advantages. There are no dependences on the development of any primarily or secondary atomic, ionic, or molecular bonds between the components materials. When these joint is operating properly, the frictional force developed precludes the fastener from having to carry and apply a bearing force by not allowing slip of the joint element. FAB 500 lb. If the interaction occurs when seen as problematic such as galvanic corrosion or galling and seizing during adhesive wear. Distribution of forces, reactions forces at pins, tension and compression etc. advantages: the behavior of connections is clear and meet assumptions of rigidity used while designing members. The process causes no chemical and microstructure will be changes in the material being joined, so dissimilar types can be combine easily, and all can be intentionally disassembled to allow maintenance, service, repair, upgrade, ultimate disposal, or portability The joining parts assemblies and a structure element is joining in structures mechanical joining, which involves two major subclasses of mechanical fastening and integral in mechanical attachment. Mechanical joining also has disadvantages such as, all mechanical joining fastening and integral attachment is that stress concentrates at the point of fastening or attachment.
