A shaft carries four rotating masses A, B, C and D which are completely balanced. The masses B, C and D are 50 kg, 80 kg and 70 kg respectively. The masses C and D make angles of 90 and 195 respectively with mass B in the same sense. The masses A, B, C and D are connected at radius 75 mm, 100 mm, 50 mm and 90 mm respectively. The plane of rotation of masses B and C are 250 mm apart. Determine: [7] a. the mass A and its angular position b. the position of planes of A and D.
