A hollow shaft of a motor is supported with bearings by the motor and extends horizontally 50mm out of the motor. The shaft has an outer diameter of 40mm and a thickness of 5mm. How much is the torque to produce a maximum shear stress of 200 MPa. Ignoring the shafts own weight, how much is the load at the suspending end of the shaft (50mm away from the bearings) that produces 300 MPa maximum normal stress on the shaft.
