torsion balance

In 1924, the torsion balance was used to locate the Nash Dome oil fields in Texas.

The D'Arsonval movement used in mechanical pointer-type meters to measure electrical current is a type of torsion balance (see below).

The torsion balance consists of a bar suspended from its middle by a thin fiber.

In the early 1900s gravitational torsion balances were used in petroleum prospecting.

Today torsion balances are still used in physics experiments.

It rather looked as if he had made his torsion balances and seismographs pay quite well for themselves.

In addition, by using spin-polarized torsion balances, the electron sector has also been tested.

More sophisticated tests use a torsion balance of a type invented by Eötvös.

The force is measured as a weight change, using a torsion balance.

To detect possible deviations in the electron sector, spin-polarized torsion balances are used.
