Point Fender A Point Fender is as a coupling element between two Bodies. The model will give: A compressive force parallel to the normal vector of the sliding plane A friction force along the sliding plane The fender can either be point symmetric, giving friction in all directions along the sliding plane, or it can be defined as a roller. In the latter case only motion parallel to the rotation axis results in friction. Possible applications are sketched in figure below. Multiple Wire Coupling Ratchet coupling
