Crushing Stress in Key is Force Due to the torque transmitting by the shaft results in shearing stress. These stresses cannot be uniform along the length of the key, due to the forces which are concentrated on the torque input end on the shaft to the hub thru the key and is represented as f c = (F*2)/(t*l) or Crushing Stress in Key = (Tangential Force*2)/(Thickness of Key*Length of Key).
