Question I have written on page kindly check them
2 = 19 (number of teeth of spur gear 3)
The motor M and the speed reducer R allow the raising of the mass Q hanged to the pulley P. Pulley P is supported by
a rope which is wrapped on the drum D on one side and on the other side is fixed to the frame.
The raising velocity v of the mass Q is constant and the efficiency of the whole system is equal to 1. Mass of pulley
P is negligible.
