Si se tiene un gato hidráulico y se aplica una fuerza en el Area 1, se refleja otra fuerza en el Area 2, teniendo en cuenta la siguiente condición A1 < A2. Podemos afirmar que las fuerzas son:

the forces are proportional to their areas of application

Explanation:

In a hydraulic jack, Pascal's principle is used, that the pressure in an incompressible liquid is the same at the same height, whereby the pressure on both sides of the jack are the same

           P₁ = P₂

the pressure is defined by

            P = F / A

we substitute

           F₂ =

therefore the force is F₂> F₁

Therefore the forces are proportional to their areas of application
