摘要
A teaching aid, designed to permit continuous activity from the manipulation of real entities - assembly, measurement and testing - to the the direct construction of associated mathematical, mechanical and physical models, consists of five sub-assemblies: a support (1) in the form of a metal frame for assembling actual or homothetic materials; a display (2) for graphic representation of associated schematic models; a drawing apparatus with a drawing board (3) for the measurement and transcription of directions, distances and trajectories related to the real phenomena on the support (1); a folding or translucent panel (4) and a fixed or adjustable frame. The support (1) is in the form of a metal plate with holes for the magnetic assembly and/or fixing with studs or screws of pulleys, dynamometers, motors, power cylinders and other equipment with an electrical, pneumatic or hydraulic power feed.
