The key observable was of course the deflection of the torsion balance rod, which Cavendish measured to be about 0.16" (or only 0.03" for the stiffer wire used mostly). [15] Cavendish was able to measure this small deflection to an accuracy of better than 0.01 inches (0.25 mm) using vernier scales on the ends of the rod. [ 16 ]
PhET Interactive Simulations is part of the University of Colorado Boulder which is a member of the Association of American Universities. [10] The team changes over time and has about 16 members consisting of professors, post-doctoral students, researchers, education specialists, software engineers (sometimes contractors), educators, and administrative assistants.

The balancing of rotating bodies is important to avoid vibration. In heavy industrial machines such as gas turbines and electric generators, vibration can cause catastrophic failure, as well as noise and discomfort. In the case of a narrow wheel, balancing simply involves moving the center of gravity to the centre of rotation
Russia has claimed that its forces captured a battered but strategic town in Ukraine’s eastern Donetsk region, a day after Kyiv launched a counterattack in the Russian region of Kursk.
The Foucault pendulum or Foucault's pendulum is a simple device named after French physicist Léon Foucault, conceived as an experiment to demonstrate the Earth's rotation. If a long and heavy pendulum suspended from the high roof above a circular area is monitored over an extended period of time, its plane of oscillation appears to change ...
Chevonne Forgan and Sophie Kirkby of the U.S. won a bronze medal in a World Cup women's doubles luge race Saturday, their second podium finish in three races this season. The Austrian team of ...
The NFL playoffs are set. After a Week 18 that saw Tampa Bay and Denver claim the two remaining playoff spots, and multiple other teams lock in their seeding, the path to the Super Bowl finally ...
A much more accurate experiment using a torsion balance was carried out by Loránd Eötvös starting around 1885, with further improvements in a lengthy run between 1906 and 1909. Eötvös's team followed this with a series of similar but more accurate experiments, as well as experiments with different types of materials and in different ...
