What torsion balance is made of
Measuring tiny forces (Coulomb, Cavendish).
- Torsion fiber — has part. A thin fibre that twists under force.
- Torsion beam with small balls — has part. Small balls on a rod.
- Large lead balls — has part. The attracting masses.
- Small mirror — has part. It reflects the beam for reading the angle.
- Elasticity — uses. The twisting of a fibre.
- Glass — is made of. The instrument is housed in a glass case.
- Silver — is made of. The suspension fibre is a thin silver wire.
