A 1-in steel shaft is loaded with combined bending and torsion: Ma = 1,024 lbf · in, Ta = 0 lbf · in, Mm = 0 lbf · in, and Tm = 995 lbf · in. Other properties include Se = 31.6 kpsi (fully corrected), Sut = 105 kpsi, Kf = 1.74, and Kfs = 1.46. Calculate the fatigue factor of safety using the DE-Goodman criterion.
