3. Please help with homework It is required that a shaft be designed to accommodate a step as indicated. The shaft is to be exposed to arotating bending moment of M = 150 Nm and a constant base torque of T = 110 Nm. The proposed designuses AISI 1045 bar stock (cold drawn) machined to the dimensions as indicated. Assume the actual endurancelimit for the machined component in the specific application to be 0.48 the estimated endurance limit of thematerial and the minimum notch diameter to be 1.5 mm.R = 2.75TmMaaUsing the Soderberg approach calculate the factor of safety of the proposed design for an unlimited life.
