Question

A 30.0-mm diameter shaft is subjected to cyclic combined bending and tor- sion loading such that M = 0.2P and T =0.15 P, where the magnitude of P varies from Pmi,--0.60 Pmax to Pmax and length is measured in millimeters. The shaft is made of a stress-relieved cold steel (o, 810 MPa 620 MPa, of safety SF 1.80, determine Pmax for 10' cycles of loading, Use the octahedral shear-stress criterion and the Gerber relation. -worked SAE 1060 = 410 MPa). Using a factor
