Theory of Machine
When a mass of a critically damped single degree of freedom system is deflected from its equilibrium position and released, then it will
Oscillate with constant amplitude
Oscillate with increasing time period
Oscillate with decreasing amplitude
Return to equilibrium position without oscillation
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.
