5. A disc cam is to be designed for a knife edge follower with the following data :

Cam lift = 60 mm during 120° of cam rotation with simple harmonic motion. Dwell for the next 30°.

During the next 90° of cam rotation, the follower returns to its original position with simple harmonic motion.

Dwell during the remaining 120°.

Draw the profile of the cam when the line of stroke of the follower passes through the axis of the cam shaft. The radius of the base circle of the cam is 60 mm. Determine the maximum velocity and acceleration of the follower during its ascent and descent, if the cam rotates at 300 r.p.m.

Draw a clear and well-proportioned Cam profile diagram, Displacement diagram
