A horizontal length of material with a vertical load system is called a beam. It is one of the most basic engineering ways of supporting a load. External forces such as the applied loads and the beam support reactions have to be in equilibrium. Given a loading system, the support reactions can be calculated from force and moment equations.

This apparatus is designed for simple experiments and demonstrations on simply supported beams. Two force gauges act as supports and enable reactions to be read directly. Six movable load hangers allow loads to be put in a number of positions.

Levers can be investigated by suspending the beam from the free standing frame, and holding
