A pulley is keyed to a shaft midway between two anti-friction bearings. The bending moment at the pulley varies  from – 170 N-m  to + 510 N-m.The shaft is made of cold drawn steel having an ultimate strength of 540 MPa and yield strength  of 400 MPa, Take σe = 0.5 σu. Determine the required diameter for an indefinite life based on Goodman equation. The actual stress  concentration factor for the keyway is 1.6. The factor of safety is 1.5.  Take size factor = 0.85 and surface finish factor = 0.88.
