A solid circular cantilever shaft is subjected to a cyclic load. The material properties are Sut = 500 N/mm2 and Syt = 260 N/mm2. The force P at the free end varies from -40 N to +120 N. Using a factor of safety of 2, corrected endurance limit stress Se = 120 N/mm2, and an amplitude to mean stress ratio of Samp/Smean = 2, determine the required diameter of the shaft.
