HFC3 Funicular Polygon and Forces Apparatus

HFC3 Funicular Polygon and Forces Apparatus

Up to five loads can be applied to the chosen shape by setting up pulleys at various angular positions. 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.

A range of experiments is possible, investigating concurrent and non concurrent coplanar forces acting on simple shapes, comparing the experimental values with the relevant polygons of force.
