The weights of four masses A, B, C, D are 200 kg, 300 kg, 240 kg, 260 kg respectively. The corresponding radii of rotation are 200 mm, 150 mm, 250 mm and 300 mm respectively and the angle between successive masses are 45°, 75° and 135°. Find the position

The weights of four masse A, B, C, D are 200 Kg, 300 Kg, 240 Kg and 260 Kg
respectively. The corresponding radii of rotation are 200 mm, 150 mm, 250 mm and
300 mm respectively and the angle between successive masses are 45o, 75o and
135o. Find the position and magnitude of the balance weight required if its radius of
rotation is 200 mm.
