Extracted text: A shaft, made of AISI 1050 CD steel, is loaded in bending and torsion such that Ma = 610 lbf · in, Ta= 375 lbf · in, Mm= 469 lbf · in, and Tm = 287 lbf· in. The shaft has a fully corrected endurance limit of S. = 30 kpsi and at the critical stress location, K= 2.3 and K = 1.9. Estimate the true fracture strength as being 50 kpsi greater than the ultimate strength. The design factor is 2.5. A) Determine the minimum acceptable diameter of the shaft using the DE- Morrow criterion. B) Determine the minimum acceptable diameter of the shaft using the DE- Gerber criterion.
