An unnotched solid circular shaft of diameter 50 mm is made of Ti-6Al-4V (yield stress =1185Mpa, ultimate stress = 2300 MPa, A= 2140 MPa and b = -.104). A zero to maximum (R=0) cyclic torque of 10KN.m is applied together with a zero-to-maximum (R=0) cyclic bending of M=7.5 KN.m Note: Bending and torque are applied in phase. a) Please determine safety factor with respect to Von-Mises theory. b) Please determine safety factor with respect to Maximum Shearing Stress Theory. c) Please determine the number of cycles to failure.

Question

The textbook we use for this class is "Shigley's Mechanical Engineering Design", Richard G. Budynas, J. Keith Nisbett,

Please help me solve this mechanical engineering problem. Thank you.

An unnotched solid circular shaft of diameter 50 mm is made of Ti-6Al-4V (yield stress
=1185Mpa, ultimate stress = 2300 MPa, A= 2140 MPa and b = -.104). A zero to maximum
(R=0) cyclic torque of 10KN.m is applied together with a zero-to-maximum (R=0) cyclic
bending of M=7.5 KN.m
Note: Bending and torque are applied in phase.
a) Please determine safety factor with respect to Von-Mises theory.
b) Please determine safety factor with respect to Maximum Shearing Stress Theory.
c) Please determine the number of cycles to failure.
