Question
A circular shaft of diameter D, groove diameter d, and groove radius r is subjected to a fully reversed torque T = 1000 Ib-in and a fully reversed moment M = 2000 lb-in. Find the factor of safety of the shaft for infinite lifetime using the modified Goodman diagram, if the shaft is made from steel (Sut = 85 ksi, Se = 45 ksi). Given: D = 2 in, d = 1 in, r= 0.5 in. Assume all fatigue stress concentration factors are equal to 1. M T M Select one: O a. N = 2.03 O b. N = 4.05 O c. N = 5.07 O d. Ne = 3.38
