It is assumed that a shaft caries four masses A, B, C and D which revolve in the same plane. The radii of rotations for these masses are 40 mm, 50 mm, 60 mm, and 30 mm, respectively. The given masses are 12 kg, 10 kg, 18 kg and 15 kg and the angular position of the masses B, C and D are 60°, 135° and 270° with respect to the mass A. Find the magnitude and position of the balancing mass. It is given that the balancing mass should rotate at a radius of 100 mm.

A disc cam is rotating in the clockwise direction with uniform angular velocity. The cam is to give uniform motion to a knife edge radial follower during out stroke of 50 mm for the first half of the cam revolution. The follower again returns to its original position with simple harmonic motion during the next half of the revolution. The minimum radius of the cam is 50 mm and the diameter of the cam shaft is 35 mm. Draw the profile of the cam. (Note: There is no Dwell for the follower motion)
