A CAM is to give following motion to knife-edge follows:

i) To raise the follower through 30 mm with uniform acceleration and deceleration during 120° rotation of the CAM

ii) Dwell for next 30° CAM rotation

iii) To lower the follower with Simple Harmonic Motion during next 90° of CAM rotation

iv) Dwell for rest of CAM rotation

The CAM rotates in counter-clockwise direction with uniform speed of 800 rpm and has minimum radius of 30 mm. Find and draw maximum velocity and maximum acceleration during outward and return stroke.
