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

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

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

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.

Theory of Machine
The factional torque for square thread at the mean radius r while raising load W is given by

T = W.r tan(φ + α)

T = W.r tan(φ - α)

T = W.r tanφ

T = W.r tanα

T = W.r tan(φ + α)

T = W.r tan(φ - α)

T = W.r tanφ

T = W.r tanα
