This apparatus comprises of a sturdy base that supports a circular table above the bench top. The table holds a large protractor and central pin. Moveable pulleys can be secured around the edge of the table. These pulleys can be secured at varying angles. Cords run over the pulleys and secure to a central ring, and Load hanger. The central ring sits over the central pin when the loads are being applied to the hangers. When the central ring is removed from the central pin, the system rests in its equilibrium position, and the lines of action of the forces are recorded by drawing along the weighted cords onto a piece of paper attached to the pulley table.
