Gravitational Torsion Balance
Combines features that significantly improve the ease of setup, the durability of the Torsion Band and the quality of results. In the newer models the spheres are tungsten rather than lead.
Following Cavendish’s classic design, PASCO’s Gravitational Torsion Balance combines features that significantly improve ease of setup, durability of the Torsion Band and the quality of results. The PASCO Torsion Band is stiffer and stronger than most bands provided with other units, however, it will eventually break. Attachment clips can be mounted to the replacement band (one is included) for quick band replacement using a screwdriver.
A Complete Manual–The Instruction Manual and Experiment Guide contains illustrated instructions for setting up and performing the measurements, plus an explanation of the theory and mathematics necessary to understand the results.
