WebThe Gravitational Torsion Balance consists of two 38.3 gram masses suspended from a highly sensitive torsion ribbon and two 1.5 kilogram masses that can be positioned as required. The Gravitational Torsion Balance is oriented so the force of gravity between the small balls and the earth is negated (the pendulum is WebTorsion balance experiments in general measure some quantity by detecting a torque on a hanging pendulum; the torque is produced by some field interacting with a dipole or higher order moment. In some of our … Eötvös's original experimental device consisted of two masses on opposite ends of a rod, hung from a thin fiber. A mirror attached to the rod, or fiber, reflected light into a small telescope. Even tiny changes in the rotation of the rod would cause the light beam to be deflected, which would in turn cause a noticeable change when magnified by the telescope. cotton booty shorts white

WebJul 22, 2024 · The torsion balance was suspended in the vacuum chamber that was placed on an inner turntable. Two pairs of attractor spheres were located on an outer, separate but coaxial turntable. The inner turntable was first rotated so that the torsion balance experienced a gravitational torque due to the interaction with the source masses. http://www.hep.vanderbilt.edu/~johnswe/classes/225a/cavmain.pdf
