Why is thecam follower position the same at the starting point and the ending point?

Answer 1

The cam follower position is the same at the starting and ending points due to the periodic nature of the cam profile. As the cam rotates, the follower moves in response to the contour of the cam, but once the cam completes a full revolution, the follower returns to its initial position. This cyclical motion ensures that the starting and ending positions of the follower align, making the system predictable and repeatable in its operation.
