1) A shaft is loaded in bending and torsion such that Ma = 70 N-m, Ta = 45 N-m, Mm = 55 N-m, and Tm = 35 N-m. For the shaft, Sut = 700 MPa and Sy = 560 MPa. A fully corrected Se = 210 MPa is assumed....

Extracted text: 1) A shaft is loaded in bending and torsion such that Ma = 70 N-m, Ta = 45 N-m, Mm = 55 N-m, and Tm = 35 N-m. For the shaft, Sut = 700 MPa and Sy = 560 MPa. A fully corrected Se = 210 MPa is assumed. Let K; = 2.2 and Kfs = 1.8. With a design safety factor of 2.0, determine the minimum acceptable diameter of the shaft using: a. DE-Modified Goodman criterion b. DE-ASME Elliptic criterion C. DE-Gerber criterion
