= 0.6 cm Suppose the shaft pictured below has dimensions d = 5 cm, D = 5.4 cm, and fillet radius r and is subjected to load P = 613 kN. Suppose the shaft is made from a material with yield strength Sy = 437 MPa. The nominal stress for this shaft is defined as nom = 4P/(d). Assuming a stress concentration factor Kt 1.8, calculate the maximum elastic stress elastic,max (i.e. assuming no yielding occurs) in the shaft: Jelastic,max = r Nb+ D Id - = MPa ? Assuming a perfectly plastic material, calculate the actual maximum stress (i.e. maximum value of load) developed in the shaft: Tload,max = MPa ? After the load is removed, find the magnitude of the maximum compressive residual stress in the shaft, residual,max: | residual,max MPa ?
