A constant-velocity cam is designed for a cycloid motion. Its follower rises 20 cm from cam angle 60° to cam angle 180° (The follower is initially at zero position). If the cam angular velocity 0, determine the velocity and acceleration of the follower at a cam angle 0. Cycloid motion equation: y = L| B 27 sin 160° 140 rpm
