A UNS G1030 steel shaft, heat treated to a minimum yield strength of 75 kpsi has a diameter of 1- 7/16 in. The shaft uniformly rotates at 600 rpm and transmits 40 hp through a gear. Find the dimensions of an appropriate key, made from the shaft material, for the gear-shaft attachment. Use a safety factor of 2.8. Your analysis should include failure due to 2 different stress type.
