| 21. | A Cavendish torsion balance is an early high-tech experiment.
|
| 22. | It does this by applying torque hydraulically to torsion bars.
|
| 23. | In 1975 the torsion box ski construction design is patented.
|
| 24. | Vehicles typically employ both hydraulic shock absorbers and springs or torsion bars.
|
| 25. | The shear modulus is also known as the torsion modulus.
|
| 26. | The Astra features a torsion beam rear suspension with Bosch.
|
| 27. | Finite locally constant sheaves are constructible, and constructible sheaves are torsion.
