2. When an electrical motor as shown in Figure 2 operates, it transmits 125 kW to the shaft at 20 Hz. The gears at B, C and D drive a machinery requiring power equal to 125/2 kW, 125/3 kW and 125/6 kW, respectively. Calculate the maximum shearing stress in the shaft and the angle of twist AD between the motor at A and gear at D if each shaft is hollow with 7.5 mm thick. Use shear modulus of 80 GPa.
