NettetFrankel, Burstein, & Brooks (1971) presented the concept of the instantaneous center of rotation, while Menschik (1974) introduced the four-bar linkage model representing the cruciate ligaments in two dimensions. Nettet7. mai 2016 · INSTANTANEOUS CENTER OF ZERO VELOCITY (Section 16-6) For any body undergoing planar motion, there always exists a point in the plane of motion at which the velocity is instantaneously zero (if it were rigidly connected to the body). This point is called the instantaneous center of zero velocity, or IC. It may or may not lie on the body!
