Abstract: An apparatus for providing progressively increasing resistance to, and automatic self centering with respect to, an operator motion input to the apparatus. The apparatus has a crossbar with a longitudinal axis and is connected to a beam with a coupling. The beam has a longitudinal axis and is cantilever mounted on a base, with the crossbar mounted in a bearing for rotation about the crossbar's longitudinal axis. The respective longitudinal axes of the crossbar and the beam are parallel to each other. The bearing is rotatably mounted in another bearing, and the first and second bearings have axes of rotation mutually perpendicular to each other. The second bearing is mounted on the base, so that the crossbar is movable about the axis of rotation of the second bearing in response to input transverse forces acting on the crossbar, and the transverse input forces thereby produce a bending moment in the first beam through the coupling.
