What system is based on Pascal's law of pressure applied to liquids in closed containers?

A hydraulic system utilizes Pascal's law, which states that a change in pressure applied to an incompressible fluid in a confined space is transmitted undiminished throughout the fluid. This principle is fundamental in hydraulic systems, where liquid, often oil, is used to transmit force. For example, when pressure is applied to a shared area in a hydraulic system, it results in a force that can be multiplied across different pistons, enabling machinery to lift heavy loads or operate various tools with relatively little input force.

This principle is what distinguishes hydraulic systems from pneumatic systems, which rely on gases and therefore are affected by compressibility and pressure variations. Likewise, turbo systems involve aerodynamic principles related to air movement, and electrical systems depend on the flow of electrical current, none of which apply Pascal's law in their operation. The application of Pascal’s law in hydraulic systems makes them particularly effective in numerous industrial and mechanical applications where force amplification is crucial.
