An instrument for measuring very weak forces by their effect upon a system of fine twisted wire.
扭秤（用来测量微力的仪器）
Example sentencesExamples
The first person to have a proper go at it was Cavendish, who managed to measure G in his famous experiment with a torsion balance about 200 years ago.
In his last years he devised a method for weighing the Earth by using a torsion balance of his own invention, but it was left to W. H. Wollaston and Henry Cavendish to carry out the experiments after his death.
These lengths of petiole were then mounted at each end in a torsion balance.
I can vaguely imagine how a massively robust nanotechnology could actually produce something like that, too - molecular-size torsion balances to sort things out and so on.
