    A Hinge connecion is the simplst type of Pivot connection
    and constrains all degrees of freedom, except the axis of rotation.
    Note that to prevent rotation about the two other axes,
    the Hinge defines constaints that will indroduce a moment.

    To simulate a more realistic Pivot connection
    see the Bearings and AxleBearings variants.
    With them realistic Bearing forces can be computed.
