In a circular arc cam with roller follower, the acceleration in any position of the lift will depend only upon
total lift, total angle of lift, minimum radius of cam and cam speed
radius of circular arc, cam speed, location of centre of circular arc and roller diameter
mass of cam follower linkage, spring stiffness and cam speed
total lift, centre of gravity of the cam and cam speed

Why not answer B, Please explain me?
Md.irfantaiyab said:   1 decade ago
Because in option B. Total angle of lift is not mentioned and acceleration also depends on total angle of lift.
Bhushan said:   8 years ago
But Radius of Circular arc is also necessary. Right? So, Option B is also Correct.
