A 1000 mm cast iron pulley is fastened to a 112 mm shaft by means of a 28 mm square key 160 mm long. The key and shaft are SAE 1030 steel annealed with allowable shearing of key at 200 MPa and compressive of 660 MPa. a. What force in lbs is required to shear the key? b. What force in kgs is needed to compress the key? c. Safe power in hp of the shaft at 600 rpm.
