EM 049 is used to investigate the fundamentals of the equilibrium of moments based on the example of a two-arm lever. Moments occurring on the lever are to be brought to equilibrium.
A centrally mounted beam represents a two-arm lever. Movable riders are placed on the lever and loads are applied. Equilibrium is attained by moving the loads. Distances from the pivot point - the lever arms - can be read from an integrated scale. The calculation of the lever arms is verified in the experiment.
A vertical column carries the lever. A sturdy base plate ensures that the unit stands securely.
The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
