The radial flat.-faced follower shown in Fig. 3.43 is made to reciprocate by the action of a circular disk cam rotating about the axis at O2.
(a) Derive expressions for the follower displacement R and for the distance t to the point of contact in terms of the cam angle θ, the radius r of the cam, and the offset distance h.
(b) Make a sketch of the displacement R versus cam angle θ for one cycle of the cam. Label the lift L of the follower as the distance from the follower's lowest position to its highest position. Give the magnitude of L.
(c) Name the type of follower motion produced by the cam.
