16–43. Determine the velocity and acceleration of platform P as a function of the angle 0 of cam C if the cam rotates with a constant angular velocity w. The pin connection does not cause interference with the motion of P on C. The platform is constrained to move vertically by the smooth vertical guides. Problem 16-43 P

A cam is to give the following motion to a knife-edged follower: 1. Outstroke during 75° of cam rotation; 2. Dwell for the next 60° of cam rotation; 3. Return stroke during the next 80° of cam rotation, and 4. Dwell for the remaining 145° of cam rotation. The stroke of the follower is 30 mm and the minimum radius of the cam is 40 mm. The follower moves with uniform velocity during both the outstroke and return strokes. Draw the profile of the cam when (a) the axis of the follower passes through the axis of the camshaft, and (b) the axis of the follower is offset by 25 mm from the axis of the camshaft. Determine the maximum velocity and acceleration of the follower during its ascent and descent, if the cam rotates at 250 r.p.m. Draw the displacement, velocity and acceleration diagrams for one complete revolution of the cam
