B2-31: EQUILIBRIUM OF TORQUES - WHEELS AND AXLES

  • ID Code: B2-31
  • Purpose: Demonstrate equilibrium of torques
  • Description:

    Two wheel and axle assemblies are provided. For each, there are cylinders of smaller radius r and larger radius R. A smaller weight m is suspended from a string wrapped around the larger radius R, and a larger weight M suspended from the smaller radius r. For equilibrium of torques:

    mR = Mr.

    On this model, radius ratios of 2:1 and 4:1 are available. A set of additional masses can be provided to vary the load.
