A compound gear train consists of four gears A, B, C and D respectively. The number

of teeth on gears A, B, C and D are TA = 54, TB = 75, TC 36 and TD = 8

respectively, out of which Gears B and C are compound gear. Determine the torque

and output power on the shaft having gear D, if the input shaft having gearA receives

9 kW at 200 rpm. Assume the train efficiency of 80%.
