Q .4 .1 .) A 40 kg mass (A) mounted on an axle at a distance of 1 m is to be balanced by two masses (B) and (C). The balancing masses are to be mounted in the planes 1 m and 2 m on either sides of 40 kg mass at radii 1 m and 2 m respectively from the axis of rotation. Find the magnitudes of the balancing masses.
