The laboratory stand is designed for carrying out laboratory works studying a part “Theoretical mechanics” of technical mechanics course at institutions of higher education with non-machine-building specialisation. The stand allows to determine value and direction of moment balancing the sum of force moments acting on a rigid body with stationary axis of rotation, to demonstrate the dependence of force moment relative to the axis on orientation of line of force action.
Structurally, the stand is made in the form of a precast base, in the central part of which there is a movable disk freely rotating relative to its center. To the movable disk with the help of cables, tensioned through the deflecting rollers, forces can be applied, which are determined by the size of the loads suspended at the ends of the cables. If the system is balanced, then when the movable disk is released, its rotation does not occur. On a fixed disk, an angular scale is applied to determine the angles of application of forces.
