The spring-held follower AB has weight W and moves back and forth as its end rolls on
Question:
The spring-held follower AB has weight W and moves back and forth as its end rolls on the contoured surface of the cam, where the radius is r and z = a sin(2θ). If the cam is rotating at a constant rate of θ', determine the maximum and minimum force the follower exerts on the cam if the spring is compressed δ1 when θ = 45o.
