Question 2 (10 marks) Design a double-dwell cam to move a follower using polynomial function for a follower that rises, from rest, through a total displacement of h mm with constant velocity for 120°, dwell for 60°, decelerates with constant deceleration for 120° until it comes to rest and dwells at zero displacement for 60º. Express s, v, and a in terms of h, 0 and B where h is the displacement, a is the angle of rotation of the cam, and B is the segment angle.
