Question $5$: Design a cam with a minimum radius of $25$ mm$,$ rotating counter clockwise at a uniform speed, is required to give a knife edge follower the motion as described below: $($marks $=3+3)$ a$)$ To move outwards through $45$ mm during $60$ rotation of the cam b$)$ To dwell for next $120$ c$)$ To return to its starting position during next $90,$ and d$)$ To dwell for the rest period of a revolution i$.$e$.90.$ The line of stroke of the follower passes through the centre of the cam shaft, and the displacement of the follower is to take place with Uniform Acceleration and Retardation motion. Draw the following: $1.$ Displacement, velocity and acceleration diagram of the follower motion $2.$ Cam profile.
