The drive shaft of the motor is made of a material having an allowable shear stress of Tallow = 75 MPa. If the outer diameter ot the tubular shaft is 20 mm and the wall thickness is 2.5 mm, determine the maximum allowable power that can be supplied to the motor when the shaft is operating at an angular velocity of 1500 rev/min.
