Q.1 A cam is to give the following motion to a flat mushroom contact face follower for part (a) and knife-edged follower for part (b): 1. Outstroke during 60 of cam rotation; 2. Dwell for the next 30 of cam rotation; 3. Return stroke during next 60 of cam rotation, and 4. Dwell for the remaining 210 of cam rotation. The stroke of the follower is 40 mm and the minimum radius of the cam is 50 mm. The follower moves with uniform velocity during both the outstroke and return strokes. Draw the profile of the cam when (a) the axis of the follower passes through the axis of the cam shaft, and (b) the axis of the follower is offset by 20 mm from the axis of the cam shaft.
