ABSTRACT:
The present invention relates to an improved rotational movement training device which includes a mounting board and a plurality of rotation devices which, when mounted on a mounting board, provide a training device which permits a user through experimentation to develop mathematical expressions and mechanical systems from elementary scientific facts and basic mathematics. The rotational devices includes gears or wheels of different diameters, pistons, torque levers, force and load pans, fulcrum-levers and devices to interconnect the wheels and pistons such as levers, belts, and adjustable spacers. The devices may be used in various combinations to develop and demonstrate mechanical movement concepts and expressions.
