A cam rotating clockwise at a uniform speed of 200 r.p.m. is required to move an offset roller
follower with a uniform and equal acceleration and retardation on both the outward and return
strokes. The angle of ascent, the angle of dwell (between ascent and descent) and the angle of
descent is 120°, 60° and 90° respectively. The follower dwells for the rest of cam rotation. The least
radius of the cam is 50 mm, the lift of the follower is 25 mm and the diameter of the roller is 10
mm. The line of stroke of the follower is offset by 20 mm from the axis of the cam. Draw the cam
profile and find the maximum velocity and acceleration of the follower during the outstroke.
