A shaft carries three masses A,B and C. Planes B and Care 60cm and 120cm from A. A, B and C are 50kg, 40kg and 60kgrespectively at a radius of 2.5cm each. The angular position ofmass B and mass C with A are 90° and 210° respectively. Find theunbalanced force and couple(Use A as reference plane). Also findthe position and magnitude of balancing masses required at 10cmradius in planes L and M midway between A and B, and B and C(Use Las reference plane).
