Some points are obvious, such as pin joints between two links. Kennedy's Theorem (Three Centres in a Line): Slideshare Restated Answer: Chapter 6 of Khurmi’s Theory
In RS Khurmi’s Theory of Machines focuses on Velocity in Mechanisms (Instantaneous Centre Method) common to two bodies
is a point, common to two bodies, that has the same velocity in each body. At a specific moment, the bodies behave as if they are rotating around this point relative to one another. 1. Identify the Number of Instantaneous Centres
at pin joints. This is the relative angular velocity between two connected links multiplied by the radius of the pin:
