The ultimate shear strength of the bolts is 250 MPa, and a factor of safety of 2 is required. Determine the minimum required bolt diameter to resist an applied load ofP = 1,300 kN. Support Bar

Just draw free body diagram

Sy= 296MPa please help solve and explain

A structural member in a nuclear reactor is made of a aluminium. An axial load of 22 kN is to be supported by the member. Use a factor of safety of 3.5 relative to yielding. EAl = 100 GPa, σy = 400 MPa. The material has elastic behavior. What is the load on the member if it is 1 mm long and its elongation is 0.5 mm?

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.
