MODEL FOR DEMONSTRATION OF THE LAWS OF THE PLANE PARALLEL FORCES

摘要

The invention relates to training aids on Theoretical and Applied Mechanics.; The technical result - improving the visibility, providing the possibility of varying the different cases of the system of parallel powers, including the power system pairs.; The model comprises a rectangular smooth horizontal plastid 1, on two opposite sides of which are fixed two blocks fixed with the possibility of displacement along the sides relative to each other and rotatably plane of each unit about its vertical axis. 1 attached to the plate line 3 on the upper surface of which has a number of pins 5 for fastening threads 6, 7 bearing hanging loads.
