Traditional Mechanisms and Mechanical Systems: Topic 3 Part 4

This video is part of a raw unedited lecture series about traditional mechanisms and mechanical systems given by Professor Jonathan Hopkins at UCLA. Specifically, Topic 3 provides the mathematics necessary to determine the velocity or speed of all the links within a mechanism consisting of rigid bodies joined together by traditional joints (e.g., prism and revolute joints) for any given configuration and input speed. Multiple analytical approaches are presented but the most powerful is the first-order kinematic-coefficient approach. Instant centers are also discussed and the Aronhold-Kennedy Theorem is introduced as a way of helping engineers find a mechanism’s instant centers. Graphical methods are also introduced that use the distances between instant centers to solve for first-order kinematic coefficients.
