A hollow steel shaft is subjected to a twisting moment (Torque) of 10677 N.m and maximum bending moment of 5423 N.m σxx = PI (L x) z ; σyy = σxy = 0 I: Inertia moment of area; P force applied at extremity σxz = P2I(h24 z2) ; σyz = σzz = 0 Find the required outside diameter d0 of the shaft to prevent yielding assuming that the inner diameter di of the shaft is to be one-half of the outer diameter (di=do/2) and the yield strength of the steel is 413 MPa: Use Tresca and Von-Mises criteria
