A, B, C and D are the four masses carried by a shaft in this order. Radii of rotation of the masses are 20 cm, 25 cm, 10 cm and 15 cm respectively. The masses of B, C and D are 3 kg, 5 kg and 4 kg respectively. The planes containing B and C are 25 cm apart. Angle between B and C is 90o and between B and D is 220o measured in anticlockwise direction. For complete dynamic balance, find (i) The mass and angular position of A, (ii) The position of planes A and D.
