EM-233 | Law of Moments Apparatus

It 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 weights are applied. Equilibrium is attained by moving the weights. 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.

Learning Objectives

• Fundamentals of the equilibrium of moments: applied forces, generated moments and equilibrium
• Action of forces dependent on the lever arm
