MODEL FOR DEMONSTRATIONS STICKS AND CLOSED REACTION FORCE PLAN

摘要

The invention relates to visual aids, and may find application in educational laboratories theoretical mechanics. In the known core structures is not possible to visually observe the resulting reaction rods and the construction plan forces applied to them. In the proposed model Front frame and rods are made of a tubular profile with longitudinal windows on each side and the arrows at the ends, inside which are located the neon lamp included in an electrical circuit with a source of electric current in the rods lamps connected in parallel, with their simultaneous turning on and off via the switch and the switch and the lamp located in the frame, equipped with individual switches and switch with the ability to enable or disable it at any time. This allows you to visually observe the resulting reaction rods and the construction plan attached to the design forces.
