Question

Problem 1: Cam Dynamics The figure below shows a simple cam- follower system. Assuming no eccentricity and acceleration due to gravity g 9.8 m/s2 and mass of follower as me 1 kg. The displacement y of the cam is given as: y(e)a1 - cos()) where a 30cm and θ refers to to angle by which cam rotates in counter clockwise direction with an angular velocity of 200rpm 1. Make a free body diagram for the follower taking gravity into consideration and write the equation of motion 2. Find the 0 where the follower loses contact with the cam 3. Can we increase the mass of the follower such that the follower always remains in contact with the cam? If yes then by how much? If no then why? Discuss 4. A lot of other methods can also be used to compensate for the loss of contact at some points. Explain one such method without changing the cam profile.
