摘要： A rotational resistance apparatus and method of use is disclosed to control movement of a carriage across a surface. The apparatus includes a disc having an axial rotational axis, an axial first end portion, and second end face portion that is substantially perpendicular to the axial rotational axis. The first end portion rotationally engages a rotating element of the carriage. Also included, is a cover having an axial longitudinal axis, an axial outer end portion that removably engages a frame of the carriage, and an axial inner face portion positioned substantially perpendicular to the longitudinal axis. The longitudinal and axial rotational axes are approximately co-axial and the inner face portion and the second end face portion are in a selected rotational frictional contact. Further included, is a first structure for selectable axial urging of the cover toward the disc, being operational to further selectably alter the selected rotational frictional contact.
