Quizplus · Accepted Answer

The instantaneous centre of rotation is a point around which two rigid links (parts of a mechanism) seem to momentarily rotate relative to each other. At this point, the two links have no relative linear velocity, meaning they are not moving away from or towards each other linearly at that instant.
