Exercise II Figure shows a round shaft subjected to a sinusoidal torque fluctuation (from 340 Nm to 790 Nm) to which it is subjected. The material is steel, with Su = 1130 MPa and Sy = 950 MPa. All cr tical surfaces are ground. Estimate the safety factor for infinite fatigue life with respect to (a) an overload that increases both mean and alternating torque by the same factor and (b) an overload that increases only the alterr ating torque. 30 mm dia. 25 mm dia. 2.5 mm rad. 1.5625 mm dia. hole. 2.5 mm rad.
