Question

Four masses 150 kg, 200 kg, 100 kg and 250 kg are attached to a shaft revolving radii 150 mm, 200 mm, 100 mm and 250 mm; in planes A, B, C and D respectively. The planes B, C and D are at distance 350 mm, 500 mm and 800 mm from plane A. The masses in plane B, C and D are at an angle 150°, 200° and 300° measured anticlockwise from mass in plane A. It is required to balance the system by placing the balancing masses in planes P and Q which are midway between the planes A and B, and between C and D respectively. If the balancing masses revolve at radius 180 mm, find the magnitude and angular position of the balance masses.

Q14/ Four masses 150 kg, 200 kg, 100 kg and 250 kg are attached to a shaft revolving at radii
150 mm, 200 mm, 100 mm and 250 mm; in planes A, B, C and D respectively. The planes
B, C and D are at distance 350 mm, 500 mm and 800 mm from plane A. The masses in
plane B, C and D are at an angle 150°, 200° and 300° measured anticlockwise from mass in
plane A. It is required to balance the system by placing the balancing masses in planes P and
Q which are midway between the planes A and B, and between C and D respectively. If the
balancing masses revolve at radius 180 mm, find the magnitude and angular position of the
balance masses.
