A shaft carries four masses A, B, C and D placed in parallel planes perpendicular to the shaft axis and in this order along the shaft. The masses B and C are 40 Kg and 28 Kg and both are at 160 mm radius. While the masses in planes A and D are at 200 mm radius. Angle between B & C is 100°, B & A is 190° and both the angles being measured in the anticlockwise (mass B is horizontal). Planes A and B are 250 mm apart, B and C are 500 mm apart. If the shaft is to be in complete balance, Using graphical method determine (i) Masses in planes A and D (ii) Distance between planes C and D (iii) Angular position of mass D.
