Theory of Machine
The essential condition of placing the two masses, so that the system becomes dynamically equivalent, is (where l₁ and l₂ = Distance of two masses from the centre of gravity of the body, and kG = Radius of gyration of the body)

l₁l₂ = kG

l₁l₂ = kG²

l₂ = kG

l₁ = kG

l₁l₂ = kG

l₁l₂ = kG²

l₂ = kG

l₁ = kG

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

All of these

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

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.
