REVIEW QUESTIONS

1. Classify with neat sketches the cam followers according to their shape, location and motion. State also their advantages, if any, with respect to other followers.

2. Sketch a cam-roller follower arrangement indicating important cam terminologies and explain them in detail.

3. Draw free hand sketches of displacement, velocity, acceleration and jerk of simple harmonic full rise motion for a cam and write the equations for displacement and its derivatives at any angle, in terms of the lift of the follower, L, and the total cam rotation angle for rise.

4. Sketch neatly the displacement,velocity and acceleration curves of a cycloidal motion followers: Why is it superior over other motion curves?

5. Explain how the cam-follower motion is selected, with their merits and demerits.

6. Sketch and briefly compare the displacement, velocity and acceleration diagrams for uniform velocity, uniform acceleration and retardation, simple harmonic motion and cycloidal motion, used in cam mechanisms.

7. Construct a tangent cam and mention the important terminologies on it.

8. Construct a circular arc cam and mention the important terminologies on it.
