What are the types of cam mechanism explain the solution with the problem

Draw the cam profile for a knife-edge follower having the followingmotion: rise 50 mm during 150 deg turn with gravitational motion, dwell for 30deg, fall 50 mm during 150 deg turn with gravitational motion, and dwell for 30deg. Use 100 mm base circle. Cam rotates clockwise. Scale 1:1

Draw the displacement diagram and profile of the cam operating a roller reciprocating follower and with the following data: Shaft diameter 10 mm; Minimum radius of cam 25mm; lift = 40mm; roller diameter=15mm. The cam lifts the follower for 120° with Simple Harmonic Motion (SHM) followed by a Dwell of 30° .Then follower lowers down during 150° of cam rotation with SHM followed by a Dwell period. If the cam rotates at a uniform speed of 100 RPM clockwise direction. Calculate the maximum velocity and acceleration during the ascent and descent period. Maximum Velocity and Acceleration During Ascent and Descent

What are the Torque equations ?
