sequence. 1. A cam, rotating at a speed of 18 rpm, is used for an exhaust valve in an engine. The cam follower must rise outward 0.5 in. with cycloidal motion in 150 of cam rotation, dwell for 30, and fall 0.5 in. with harmonic motion in 180 of cam rotation, and then repeat the Determine the time consumed during each follower motion. Derive the displacement, velocity and acceleration equations for each interval. Also, graphically plot a follower displacement diagram.
