2. A Rotating shaft carries four masses A, B, C and D which are radially attached to it. The mass centres are 30 mm, 38 mm, 40 mm and 35 mm, respectively from the axis
of rotation. The masses A, C and D are 7.5 kg, 5 kg and 4 kg, respectively. The axial
distances between the planes of rotation of A and B is 400 mm and between B and C
is 500 mm. The masses A and C are at right angles to each other. Using either
graphical or analytical methods, determine, for complete balance:
a. The angles of the masses B and D from mass A
b. The axial distance between the planes of rotation of C and D
c. The magnitude of mass B​
