Q1:

In a cam drive with uniform velocity follower, the sharp corners of the displacement diagram are rounded off at the beginning and at the end of each stroke. This is done

A because of difficulty in manufacturing cam profile

B because of loose contact of follower with cam surface

C in order to have acceleration in beginning and retardation at the end of stroke within the finite limits

D because the uniform velocity motion is a partial parabolic motion

ANS:C - in order to have acceleration in beginning and retardation at the end of stroke within the finite limits
