If the bolt head and the supporting bracket are made of the same material having a failure shear stress of Tfail = 150 MPa,
determine the maximum allowable force P that can be applied to the bolt so that it does not pull through the support. Apply a
factor of safety of F.S. = 2.5 against shear failure.
Express your answer to three significant figures and include the appropriate units.
The cotter is used to hold the two rods together. Determine the smallest thickness t of the cotter and the smallest diameter d of the rods. All parts are made of steel for which the failure of normal stress is sfail = 500 MPa and the failure shear stress is tfail = 375 MPa. Use a factor of safety of (F.S.)t = 2.50 in tension and (F.S.)s = 1.75 in shear.
