Equilibrium of Forces

A force board is clamped into the working area of Universal Frame and Stand single and double pulleys sets can be fixed round the perimeter of the to produce an infinite variety of multi-directional forces in a vertical plane. Two cord rings held together by a short cord are used for non-concurrent force experiments. The lines of action of the cords are transferred onto a sheet of paper clipped to the force board using the board clips provided. By using a single cord ring (concurrent forces), up to six cords can be attached and the cords tensioned with load hangers and weights to obtain Equilibrium of Forces. The set of weights for the experiment is included.

Experimental Capabilities:
Equilibrium of up to six non-concurrent forces
Experimental verification of the three conditions of equilibrium, i.e. Fx = 0; Fy = 0; Mx = 0 (where F = forces and M = moments)
Equilibrium of a set of forces acting in a vertical plane
Graphical solution of a triangle of forces (three forces) or closed polygon for more than three forces
Equilibrium of up to six concurrent forces.
Construction of polygon of forces
Link polygon.
