= 2. (Point 50) A shaft is loaded in bending and torsion such that Ma = 70 Nm, Ta 45 Nm, Mm = 55 Nm, and Tm = 35 N m. For the shaft, Su = 700 MPa, Sy = 560 MPa, the true fracture strength is 1045 MPa, and a fully corrected endurance limit of Se=210 MPa is assumed. Let K = 2.2 and K = 1.8. With a design factor of 2.0 determine the minimum acceptable diameter of the shaft using the (a) DE-Goodman criterion. (b) DE-Morrow criterion. (c) DE-Gerber criterion. (d) DE-SWT criterion. Discuss and compare the results.
