3) A circular rotating shaft has an alternating bending moment of 20e3 in-lbf and a steady torque of 10e3 in-lbf at the critical location. There are no stress concentrations. The shaft is made from 1050 steel with a machined surface finish, St = 100 kpsi, and S, = 84 kpsi. ut a) Specify the diameter that will give a factor of safety of 1.5 against fatigue failure (i.e. infinite life), using 95% reliability. b) Determine the factor of safety for yielding for the diameter you found in part a Note this problem will probably require iteration. The use of spreadsheets (or matlab) is recommended.
