Fasteners and Design of Non Permanent Joints

Fasteners are described as mechanical components used to join or assemble two or more pieces of materials. The fasteners are used in various machines or structures based on their suitability to produce non-permanent, semi-permanent, and permanent joints.

Question

4. Determine the design stress for bolts in a cylinder cover where the load is fluctuating due to gas
pressure. The maximum load on the bolt is 50 kN and the minimum is 30 kN. The load is unpredict-

A tensile-testing apparatus is to be constructed that must withstand a maximum load of 293516 N. The design calls for two cylindrical support posts, each of which is to support half of the maximum load. Furthermore, plain-carbon(1045) steel ground and polished shafting rounds are to be used; the minimum yield and tensile strengths of this alloy are 343 MPa and 565 MPa(82,000 psi), respectively. Specify a suitable diameter in mm for these support posts. Assume safety level is 2.3. Round your answer to 2 significant figures.

Two parts of a machine, both made from steel, are held together by 5 equally-spaced M6 x 1.0 grade 8.8 bolts that are uniformly tightened to provide a total initial clamping force of 23 kN in the members. Each bolt has a proof stress of 600 MPa, and a tensile area of 20.1 mm². The elasticities are such that the joint constant is 0.2. A uniform static tensile load of 12 kN is applied to the entire joint after it has been preloaded. What is the magnitude of the total clamping force in the joint after the application of the tensile load? Express your answer in units of kilonewtons.
