For their measurements, which have an uncertainty of about . 0015 percent, the University of Washington researchers used an improved version of a torsion balance.

He lowered a crystal on a glass fiber attached to a torsion balance into a solution whose magnetic susceptibility could be varied between two magnetic poles.
23.
To find the torsion coefficient ( " ? " ) of the wire, Cavendish measured the natural oscillation period " T " of the torsion balance:

The most important advance in experiments on gravitation and other delicate measurements was the introduction of the torsion balance by Michell and its use by Cavendish.
25.
In essence, the torsion balance measures the force of some external agent acting on a suspended object by measuring the torque, or twist, on that object.

Francis Ronalds, the inaugural Director of the Kew Observatory, made important improvements to the Coulomb torsion balance around 1844 and the modified instrument was sold by London instrument-makers.
27.
In an experiment not dissimilar from others mentioned above, Paliwal " et al . " constructed a molecular torsion balance from an aryl ester with two conformational states.
28.
To guard against the influence of air currents, the apparatus ( called a torsion balance ) was enclosed in a room and observed with telescopes mounted on each side.

This corporation remained in existence until the year 1943 when it was dissolved in the manner later des�cribed; and it, thereupon, became a division of the Torsion Balance Company.

During the solar eclipse of January 26, 2009, a correlation was found between anomalous behavior of a pendulum and torsion balances, located at two different points outside the shadow zone.
