The laboratory stand is designed for carrying out laboratory works in technical mechanics for machine-building specialties at secondary educational institutions. It allows to investigate system of converging forces, to determine value and direction of equal force balancing the investigated system.
Structurally, the training system is made in the form of a precast base, in the central part of which there is a disk with a hole for mounting the pin. The pin serves to fix the washer, to which with the help of cables, stretched through deflecting rollers, forces are applied, determined by the size of the loads suspended at the ends of the cables. Thus, the washer is the center of the system of converging forces, and if the system is balanced, then when removing the pin, the washer will remain in the center of the disk. The disc has a goniometric scale to determine the angles of forces application.
