The short answer. From the late 1700s to the present day, scientists have measured the strength of the gravitational force using different versions of a sensitive laboratory instrument known as a torsion balance, in . When the torsion balance was released and allowed to move freely, the lead balls would be attracted by the gravitational force.

Figure 6. Optomechanical torsion balance. Panel (a) shows a sketch of a torsion pendulum with a dumbbell-shaped body suspended from a thin wire with torsion constant τ.A magnetic damper attached to the wire damps mechanical modes other than the torsional one [].Panel (b) presents a scheme of the optomechanical system composed of the torsion . This is how the Simple Gravity Variometer was born in 1898 which was later renamed the Balaton balance . It was also due to Hugo Böckh’s proposal that a test of the usefulness of torsion balance exploration was set .
We used a continuously rotating torsion balance instrument to measure the acceleration difference of beryllium and titanium test bodies towards sources at a variety of distances. . (upper part). The entire torsion balance is suspended below a continuously rotating turntable. Gravity gradient compensator masses were placed around the pendulum .Ground-based self-gravity tests for LISA Pathfinder and LISA C Trenkel, C Warren and D Wealthy Astrium Ltd, Gunnels Wood Road, Stevenage SG1 2AS, UK . • Gravitational II – direct coupling to “far” torsion balance test mass which is not infinitely far The first four effects are standard effects, and well-known procedures exist for .1x X-Y Adjustable Diode Laser The Gravitational Torsion Balance requires a laser.

The value of G was not experimentally determined until nearly a century later (1798) by Lord Henry Cavendish using a torsion balance. Cavendish's apparatus for experimentally determining the value of G involved a light, rigid rod about 2-feet long. Two small lead spheres were attached to the ends of the rod and the rod was suspended by a thin wire.Most torsion balance experiments employ unpolarized test bodies either of different composition to test the universality of free fall or of special geometry to test for violations of the 1/r2 law of gravity.1 There are several motivations, however, to perform similar torsion balance measurements with spin polarized test bodies: to help . Cavendish demonstrated this using a torsion balance, a horizontally suspended wooden rod with a small lead sphere at each end. Two large lead spheres were fixed in place, 9 inches from each of the . In order to replicate the Cavendish Experiment and experimentally determine a value for the universal gravitation constant, I build a torsion balance. This .
In this type of gravity experiments, the torsion balance is a very powerful tool to test the gravitational ISL at short ranges. By using the schemes of the separation modulation or rotation modulation, the Yukawa effects to be measured are kept in . In his famous 1798 paper 3, he described an experiment to weigh the Earth using a torsion balance or, as we would now say, to determine G.

To control the spacecraft and to distinguish locally induced noise from the science signal . To study the linearity of gravity gradients, torsion balance measurements were made both at the field and in a laboratory: one is at the southern part of the Csepel island, and the other in the .
We pioneer new techniques to test weak-field gravity, search for new interactions weaker than gravity, and develop instrumentation for LIGO. . Torsion Balance Test of Spin-Coupled Forces Physical Review Letters 97, 021603 (2006) Measurement of the gravitational constant Phys. Rev. Lett 85 2869 (2000) This paper discusses experimental results of Mach-Effect-Thrusters (MET), or Mach-Effect Gravity Assist (MEGA) drives, on sensitive torsion balances. Recent experimental results disagree with the theory developed by Woodward and the experimental artefacts are characterized, building up on previous test campaigns [7].Since the late 18th century when Cavendish performed his measurements of the force of gravity, torsion balances have been apparatus of choice for precision measurements of the force between two test bodies. Our group specializes in . As is well known, on small scales gravity is much weaker than the other three fundamental forces, making it difficult to test at short distances. In fact, the gravitational interaction has only been probed down to ∼0.1 mm, with torsion-balance tests of the inverse square law [10].
The theory was first proposed by Élie Cartan in 1922 [3] and expounded in the following few years. [4] [5] [6] Albert Einstein became affiliated with the theory in 1928 during his unsuccessful attempt to match torsion to the electromagnetic field tensor as part of a unified field theory.This line of thought led him to the related but different theory of teleparallelism. The beam balance is similar to our torsion balance 43 with a lever arm length of 338 mm. The box uses unannealed mu-metal plates for electrostatic shielding and provides an internal volume of 24.0 .
An earlier scientist, John Michell, had used a similar instrument to study gravity, but the device did not gain much fame until after Coulomb reinvented it and put it to a different use. . In fact, the torsion balance became one of the most popular scientific instruments to grace laboratories in the late 18th century and throughout the . Based on the principle of torsion balance measuring gravity gradient, designed a torsion balance gravity gradiometer, consisting of a torsion balance system, an angle measurement system, an . equivalence test was aimed to check composition dependence of the gravitational force. It was designed to be free from any bias related to the possibly .Another type of ISL test gravity experiments is the test of the gravitational inverse-square law in the laboratories. In this type of gravity experiments, the torsion balance is a very powerful tool to test the gravitational ISL at short ranges.

The angular position of the torsion balance is read out by means of an optical lever using 1.8 mW of laser light (Innolight Mephisto) with an angle of incidence of ~50 mrad. . (titanium gravity .
Experiments with ordinary pendulums test the principle of equivalence to no better than about one part in 10 5.Eötvös obtained much better discrimination with a torsion balance. His tests depended on comparing gravitational forces with inertial forces for masses of different composition.Eötvös set up a torsion balance to compare, for each of two masses, the .

We briefly summarize motivations for testing the weak equivalence principle and then review recent torsion-balance results that compare the differential accelerations of beryllium–aluminum and beryllium–titanium test-body pairs with precisions at the part in 1013 level. We discuss some implications of these results for the gravitational properties of .
