## Sample Question from ME8492 Question Paper Kinematics Of Machinery:

1. A cam is to give the following motion to a knife edged follower: (a) Outstroke during 60° of cam rotation (ME8492 Question Paper Kinematics Of Machinery)
(b) Dwell for the next 45° of cam rotation
(c) Return stroke during next 90° of cam rotation and
(d) Dwell for the remaining of cam rotation ME8492 Question Paper Kinematics Of Machinery
The stroke of the follower is 40 mm and the minimum radius of the cam is 50 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 cam shaft, and (b) the axis of the follower is offset by 20 mm from the axis of the cam shaft. (ME8492 Question Paper Kinematics Of Machinery)

2. Draw the profile of a cam operating a Knife-edged follower from the following data: (ME8492 Question Paper Kinematics Of Machinery)
(a) Follower to move outward through 40 mm during 60° of a cam rotation; (b) Follower to dwell for the next 45° (c) Follower to return its original position during next 90° (d)Follower to dwell for the rest of cam rotation. The displacement of the follower is to take place with simple harmonic motion during both the outward and return strokes. The least radius of the cam is 50mm. If the cam rotates at 300 r.p.m., determine the maximum velocity and acceleration of the follower during the outward stroke and return stroke. (16) (ME8492 Question Paper Kinematics Of Machinery)

3. A cam, with a minimum radius of 50 mm, rotating clockwise at a uniform speed, is required to giver a knife-edged follower the motion as described below: (a) To move outwards through 40 mm during 100° rotation of the cam; (b) to dwell for next 80° (c) To return to its starting position during next 90 ° and (d) To dwell for the rest period of revolution. Draw the profile of the cam (i) When the line of stroke of the follower passes through the centre of the cam shaft and (ii) When the line of stroke of the follower is to take place with Uniform acceleration and uniform retardation. Determine the maximum velocity and acceleration of the follower when the cam shaft rotates at 900 r.p.m. (16) (ME8492 Question Paper Kinematics Of Machinery)
