ID Code: B2-31
Purpose: Demonstrate equilibrium of torques
Description: Two wheel and axel 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.

Numerical values are written on the apparatus.
