tating steel shaft has endurance limit of Se = 343 MPa and ultimate strength of Sut = 627 MPa. A section of the shaft with dimensions is shown in the figure (D=38.5 mm, d = 35 mm, r = 3.5 mm). The section is subjected to a completely reversed bending moment of 192 Nm, accompanied by a torque alternate from 0 to 203 Nm. Calculate the fatigue factor for an infinite life using the Goodman criterion. Orientation: Use Excel spreadsheets to calculate the theoretical stress concentration factors and the notch sensitivities parameters. Bending moment Torque 203 Nm- r = 3.5 mm 192 Nm =38.5 mm = 35 mm 0 Nm. -192 Nm. pulsating cycle reversed cycle
