Solve Problem 4.31 using the octahedral shear-stress criterion of failure.

Problem 4.31

A load P = 30.0 kN is applied to the crankpin of the crankshaft in Figure P4.31 to rotate the shaft at constant speed. The crankshaft is made of a ductile steel with a yield stress Y = 276 MPa. Determine the diameter of the crankshaft if it is designed using the maximum shear-stress criterion for initiation of yielding and the factor of safety is SF = 2.00.
