Quiz3 : Cam Profile SHM 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.

Quiz3 : Cam Profile SHM
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.
