Figure Q1 shows a shaft carrying 5 uniform discs: A,B,C,D, and E, each of mass 10 kg. Initially the centre of mass is at the axis of rotation. Modifications are made on the discs as follow: Disc C remove 0.2 kg at radius 0.2 m and 0 = 180 Disc D add 0.1 kg at radius 0.2 m and 0 = 90 For complete balance, determine the masses (magnitude and direction) to be added to disc A and E, both at radius 0.1 m.
