Hydraulics (Pascal’s law)
principle · 1653 · Early modern era
Pressure in a liquid is transmitted equally in all directions.
Principles and materials it uses
- Pressure — uses. Pressure is transmitted through a liquid.
Where it is used
- Hydraulic press — is used in. Pascal’s law multiplies the force.
- Jack — is used in. A hydraulic jack.
- Shock absorber — is used in. Oil flows through valves, damping oscillations.
- Injection moulding — is used in. Hydraulic presses.
- Manometer — is used in. A liquid manometer is a pair of communicating vessels: the difference in levels shows the pressure.
- Recoil mechanism — is used in. A hydraulic recoil brake.
- Power steering — is used in. Hydraulic power steering.
- Hydraulic brake — is used in. Pascal’s law.
- Door closer — is used in. Hydraulic damping.
- Hydraulic fracturing — is used in. Fluid pressure.
- Wave power station — is used in. Hydraulic converters.
- Hydraulic cylinder — is used in. The liquid transmits pressure to the piston.
- Forging press — is used in. Hydraulics does the pressing.
