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
-
In a steam engine, the earlier cut-off with a simple slide valve may be obtained by increasing the angle of advance of the eccentric but reducing the throw of the eccentric and keeping the steam lap and exhaust lap constant. This method will cause withdrawing or throttling of steam.

A governor is said to be stable, if the

Which of the following statement is correct?
-
A point B on a rigid link AB moves with respect to A with angular velocity ω rad/s. The radial component of the acceleration of B with respect to A, is (where vBA = Linear velocity of B with respect to A)

The relation between me number of links (l) and the number of binary joints (j) for a kinematic chain having constrained motion is given by l = l - 2. If the left hand side of this equation is greater than the right hand side, then the chain is
