(ii)Follower dwells for next 45o.
(iii)Follower to return to its original position during next 90o.
(iv)Follower to dwell for rest of the rotation. The displacement of follower is
to take place with simple harmonic motion during both outward and

rpm.
Lift (S) = 40 mm
Outward Stroke (θo) = 60o
Dwell (θ D) = 45o
Return Stroke (θ R ) = 90o.
Base Radius of Cam (R) = 50 mm
