🔄 Disc Cam: Dwell-Rise-Dwell-Return Motion Laws and Pressure Angle (2D)

A rotating disc cam with a roller follower that rises, dwells at the top, returns and dwells at the bottom, with four selectable motion laws. Set the lift, the angles of each segment, the speed, the follower mass and the prime circle, and see the velocity, acceleration, inertia force and pressure angle all the way round. Peak velocity, peak acceleration, lift by integration and the zero net inertia work are checked numerically, with four in-page numerical checks.
