Hydraulic lift principle.

Pressure is the force applied perpendicular to an object per unit area: P= F / S . P is expressed in N/m^{2} or "pascal" (Pa).

The surface of the right piston is 5 times greater than the left one. The resulting force is 5 times larger.

Pressure applied to an enclosed fluid is transmitted undiminished to every portion of the fluid and the walls of the containing vessel (Pascal's law). Don't confuse the blue arrows (representing individual forces on some portions of the walls (vectorial value) ) and pressure (scalar value).

**Pressure **is the ratio between the force exerted and the area of the surface withstanding the force. **Hydraulic lifts** operate according to **Pascal’s law**, which states that pressure applied anywhere…
