Theory of Machine
Which of the following property of the instantaneous center is correct?

All of these

The velocity of the instantaneous centre relative to any third rigid link is same whether the instantaneous centre is regarded as a point on the first rigid link or on the second rigid link.

The two rigid links have no linear velocity relative to each other at the instantaneous centre.

A rigid link rotates instantaneously relative to another link at the instantaneous centre for the configuration of the mechanism considered.

Theory of Machine
The Grubler's criterion for determining the degrees of freedom (n) of a mechanism having plane motion is (where l = Number of links, and j = Number of binary joints)

n = (l -1) - j

n = 2(l - 1) - 2j

n = 4(l - 1) - 3j

n = 3(l - 1) - 2j

n = (l -1) - j

n = 2(l - 1) - 2j

n = 4(l - 1) - 3j

n = 3(l - 1) - 2j
