POLYGON and FORCES APPARATUS Model MT 087
POLYGON and FORCES APPARATUS Model MT 087
Sci-tech Polygon and Forces Apparatus Model MT 087 consists of a circular table above the bench top. The table supports a large protractor and central pin. Around the edge of the table can be secured movable pulleys. 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. The loads are applied using the hangers and cords provided, with the cords easily connecting to the shapes by the use of the small hooks provided. Two additional shapes are provided to expand the student learning into link polygons for three or more non-concurrent coplanar forces.

Experiments
- To resolve by experiment any suitable system of static coplanar forces which may or may not be concurrent.
- To verify graphically using:
- a) triangle of forces for three concurrent coplanar forces
- b) polygon of forces for more than three concurrent coplanar forces
- c) link polygon for three or more non-concurrent coplanar forces
- To investigate © for either a disc or a rectangular shape
- To compare the accuracy of the experiment by comparing the experimental and graphical results
