One Way Rotational Clutch

Parallel connection of freewheel and clutch

Description

The One Way Rotational Clutch (or One Way Clutch) component models a one-way clutch, which is a clutch connected in parallel to a free wheel.  This special element is provided because such a parallel connection introduces an ambiguity to the model (the constraint torques are not uniquely defined when both elements are stuck) and this element resolves it by introducing one constraint torque instead of two. See the Clutch model for the basic model description.
