This is briefly expressed as follows: Harmonic rise 120° Rest 60° Uniformly accelerated and retarded fall 150° Rest.. 30° 1. Follower Positions. The length of travel Ae being known, it is divided for purposes of the rise,… … Fig. 90. Diagram of Complex Motion Plate Cam distances giving harmonic motion of the follower; and for purposesof the fall, by the principles of Fig. 89, into distances giving uniformlyaccelerated and retarded motion. Eight spaces are chosen, so thatthe process of making these divisions is an exact…
