A cam operates a roller follower, axis passing through theaxis of cam.
     The specifications are
     Minimum radius of cam = 25 mm
     Lift of follower = 30 mm
     Diameter of roller = 15 mm
     Angle of lift = 120 o with SHM
     Outer dwell angle = 30 o
     Angle of return = 150 o with uniform
     acceleration and retardation.
