Parameters

Description

The Lever component represents a mechanical lever. The parameters lenAB and lenBC assign the effective lever lengths between flanges.

The boolean parameter absolute determines whether the motion constraint is absolute or relative. Absolute constrains the positions, relative constrains the velocities.
