6. A marine turbine developing 15,000 hp and it turns the shaft at 300 rpm. The propeller which is attached to the shaft develops a thrust of 150,000 lbs. A hollow steel shaft with an outside diameter of 14 in. will be used. The maximum shearing stress based on the torsion alone is not to exceed 7.5 ksi. Find the thickness of the hollow shaft in mm.
