Equilibrium Of Torques - Wheels And Axles
To demonstrate equilibrium of torques.
Wheel and axel assemblies with weights and strings, as photographed.
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.
