A 12.6 inches long key is to be used on a 210 hp, 1200 rpm, slip ring induction motor. The key is 1 in wide and has a depth of 3/4 in. The shaft diameter is 3 7/8 inches. The maximum running torque is 200% of the full-load torque. 1. Determine the maximum compressive (crushing) stress of the key, in psi. 2. Determine the maximum direct shearing stress on the shaft, considering the effect of the keyway, in psi
