WebThe force–balance principle is used to create pneumatic amplifiers, transmitters, and relays. In addition spring (control) ranges are used to sequence devices. Many different spring ranges are available. A full range spring would typically have a 3–13 psig rating. More commonly, partial ranges are used; typically 3–8 psig, 5–10 psig ... Webaccurate force measurement, using a torsional balance, between two small, charged metal spheres. He adjusted the distance between the spheres and measured the force with the balance. Coulomb probably invented this sort of balance, which has been used ever since in measurement of very small forces. 30 August 2024 Physics 122, Fall 2024 3 cherry laurel athens tx menu

"WebMar 13, 2011 · Though the simple gravitational and electrostatic forces may be balanced, there is an additional effect for the electrical interaction that won't exist for gravity: the charge of each sphere polarizes the other. The charge distributions on each sphere adjust themselves for minimal energy, and that leads to a feeble but non 1/r^2 attractive force. " - Electrostatic force balance
