Four masses A, B, C and D equally spaced along a shaft revolve at equal radii. The mass of B is 7 kg. The radii of masses C and D make an anticlockwise angle of 90° and 240° respectively with the radius of B, which is horizontal. For complete balance and using mass A as a reference, find: 2.1. The magnitude of mass C and mass D. 2.2. The magnitude and angular position of mass A. Use the analytical method.
