B2-31: EQUILIBRIUM OF TORQUES - WHEELS AND AXLES

PURPOSE: To 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.

SUGGESTIONS:

REFERENCES: (PIRA 1J40.27)

EQUIPMENT: Wheel and axel assemblies with weights and strings, as photographed.

SETUP TIME: None.
