Problem 2 A machine component is modeled as a simply supported solid round rotating shaft with diameter D = 1.2 inch, and length L = 15 inch made from AISI 1050 cold drawn steel with a machined finish. A concentrated transverse load of F = 1200 lbf is acting at the central midpoint length (L/2) of the shaft, such that completely reversing bending stress is occurring. Using the Goodman failure criteria, determine the fatigue life of the shaft at an operating temperature of 675 deg F, with a reliability of 90%, and also check for yielding,
