This equipment provides a simple easy to understand experiment on the equilibrium of moments. Several loads can be put on the beam at various positions. These will make the beam rotate. The student has to determine the moment necessary to overcome this rotation and keep the beam level.
On a practical level, this principle is used in the measurement of goods, such as in chemical balances and steelyards.
The alloy beam is 530mm long and graduated in each direction from the central pivot in cm. Three wire stirrups; weight hangers and a set of weights are included.
