How does Pascal's law work?

Applied to a more complex system below, such as a hydraulic car lift , Pascal's law allows forces to be multiplied. The cylinder on the left shows a cross-section area of 1 square inch, while the cylinder on the right shows a cross-section area of 10 square inches. The cylinder on the left has a weight (force) on 1 pound acting downward on the piston, which lowers the fluid 10 inches. As a result of this force, the piston on the right lifts a 10 pound weight a distance of 1 inch.

How does a 10 pound piston work?

The 1 pound load on the 1 square inch area causes an increase in pressure on the fluid in the system. This pressure is distributed equally throughout and acts on every square inch of the 10 square inch area of the large piston. As a result, the larger piston lifts up a 10 pound weight. The larger the cross-section area of the second piston, the larger the mechanical advantage, and the more weight it lifts.

Some aircraft utilize pneumatic systems for their brakes, landing gear and movement of flaps.

How do hydraulic brakes work?

Hydraulic brakes work on the principle of Pascal’s law. According to this law whenever pressure is applied on fluid it travels uniformly in all the directions. Therefore when we apply force on a small piston, the pressure gets created which is transmitted through the fluid to a larger piston. As a result of this larger force, uniform braking is applied on all four wheels. As braking force is generated due to hydraulic pressure, they are known as hydraulic brakes. Liquids are used instead of gas as liquids are incompressible.
