Theory of Machine
Which is the false statement about the properties of instantaneous center?

The two rigid links which have no linear velocity relative to each other at this center have the same linear velocity to the third rigid link
The double center can be denoted either by O2 or O12, but proper selection should be made
At the instantaneous center of rotation, one rigid link rotates instantaneously relative to another for the configuration of mechanism considered
