Torsion balance

Torsion balance , device used to measure the gravitational acceleration at the Earth’s surface. Other such devices, using different methods to obtain the same result, are pendulums and gravimeters. In some of our balances, we exploit a composition dipole to test for composition-dependent forces. Coulomb’s torsion balance consists of several small parts, pictured at right.

More example sentences ‘In his last years he devised a method for weighing the Earth by using a torsion balance of his own invention, but it was left to W. Wollaston and Henry Cavendish to carry out the experiments after his death. If the only other forces acting on the weights also pull straight down, they won. It measured the force of gravity between masses M and m, yielding the value of the gravitational constant G. Labels: (M) mass of stationary lead balls, (m) mass of movable lead balls, (F) gravitational force between each pair of balls, angle of deflection of balance from equilibrium. The apparatus constructed by Cavendish was a torsion balance made of a six-foot ( m) wooden rod horizontally suspended from a wire, with two 2-inch (mm) diameter 1. Charles Augustin de Coulomb, Encyclopædia Britannica.

Cavendish used the Coulomb torsion balance for gravitational measurements and determined the constant of gravitation. Regional and areal torsion-balance surveys can be used to map most. The torsion balance has been used with distinct success to map the buried gra. We supply two models of direct reading balance for the measurement of mass and surface tension.
