Princípio de Pascal (prensa hidráulica)

This calculator applies Pascal's Principle to determine the force exerted by a hydraulic press. Pascal's law states that pressure applied to a confined fluid is transmitted equally in all directions. In practice, a small force applied over a small area can generate a much larger force over a larger area, provided the fluid is incompressible. The formula used is F₂ = F₁ · A₂ / A₁, where F₁ is the input force, A₁ is the input piston area, A₂ is the output piston area, and F₂ is the resulting force.

To use the tool, enter values for F₁, A₁, and A₂. The calculation automatically returns the force F₂. For example, if you apply 100 N on a piston of 0.01 m² and the output piston has 0.1 m², the output force will be 1000 N, multiplying the force by 10. This shows how the hydraulic press amplifies force, useful in jacks, brakes, and hydraulic lifts.

Common use cases include sizing hydraulic systems in auto shops, designing vehicle lifts, and industrial pressing equipment. The calculator helps predict the force needed to lift a weight or the force a hydraulic cylinder can exert. Remember that areas must be in the same unit (m², cm², etc.) and that real efficiency may be lower due to friction and leaks.

Important precautions: ensure area units are consistent; always use the same system (m² with m², cm² with cm²). The formula assumes incompressible fluid and no losses; in practice, consider a safety factor. Do not confuse diameter with area: piston area is π·r². For accurate calculations, measure cylinder diameter and calculate the area correctly.
