What is another word for torsion balance?
Pronunciation: [tˈɔːʃən bˈaləns] (IPA) 
A torsion balance is a scientific instrument that measures very small forces or changes in gravitational pull. There are several synonyms for torsion balance, including torsion pendulum, torsion spring balance, and Coulomb balance. A torsion pendulum is a type of torsion balance that uses a pendulum to measure changes in gravitational force. A torsion spring balance uses a spring instead of a pendulum to measure forces. The Coulomb balance is a type of torsion balance that measures electrical forces between charged objects. All of these instruments rely on the same basic principle of torsion, which is the twisting of a wire or spring to measure tiny forces.
