Q3: A cam, with a minimum radius of 50 mm, rotating clockwise at a uniform speed, is required to give a knife edge follower the motion as described below: 1. To move outwards through 40 mm during 100" rotation of the cam 2. To dwell for next 80° 3. To return to its starting position during next 90 4.To dwell for the rest period of a revolution i.e. 90°. a. Draw the follower displacement diagram by graphical method if the displacement of the valve, while being raised and lowered, is to take place with uniform acceleration and uniform retardation. b. Draw the profile of the cam. c. Determine maximum velocity and acceleration using analytical method (by using formulae), Take N= 200RPM
