The following questions are about the data presented in Figure 2. (a) Cyclic compressive and tensile stresses are applied axially on a cylindrical shaft made of 1045 steel. If the amplitude of the applied force is 66 700 N calculate the minimum diameter for the shaft that will not exhibit any fatigue damage. (b) Cyclic compressive and tensile stresses are applied axially on a cylindrical shaft with a diameter of 6.4 mm made of 2014-T6 aluminum alloy. Maximum tensile force is +5340 N and the maximum compressive force is-5340 N. Calculate the fatigue life of the part.
