Draw the displacement-time graph for a follower that rises 19 mm with simple harmonic motion in a quarter revolution, dwells for an eighth revolution, and then rises 19 mm with simple harmonic motion in a quarter revolution of the cam. The follower dwells for a sixteenth revolution and then returns 38 mm with parabolic motion in a quarter revolution, followed by a dwell for a sixteenth revolution of the cam. Use an abscissa 160 mm long.
