5.6.7. Cylindrical Joint Properties

Relative motion and connector parameters can be modified from the Cylindrical Joint property dialog. The T-Relative and R-Relative tabs are exactly same as those of a Translational Joint and Revolute Joint, respectively.

Parameters for T-Friction are defined as shown in the figure and table below.
