Many of us often wondered how some technological advances, such as the hydraulic jack, work. The secret is simple and has nothing to do with complex mechanisms. This device, like many others, works on the basis of the Blaise Pascal principle, that in a closed container the pressure is the same at all points. The mathematical pressure is described by the Force divided by the Region. This means that if you have two connected cylinders — large and small, and apply some force to the second, this will lead to pressure, and since it will be the same at all points, the large cylinder will be under the same pressure,
Hydraulic jacks use this principle and work with the force allocated by a larger container, and also because it has a larger area, the force produced is also greater. It turns out that if there is a big difference in the areas of the cylinders used, the power of the potential force larger will be much more powerful. Therefore, this device is designed in a very simple way - two connected cylinders and the answer to how it works is leakage. The pressure described above is the result of the following: the cylinders are filled with pressurized fluid, which exert the same pressure through its volume and on the surface of the cylinders contained in it. This compressed fluid is usually oil because it lubricates the system and is forced into the cylinders with the help of a plunger. When this happens, the fluid passes through the valve pump. When the plunger goes down, it directs the fluid to another valve in the cylinder.
It is for this reason that these devices can generate a large force, applying a small force to it. If a small square inch piston applies a weight of one pound to hydraulic fluid, it will provide a pressure of 1 pound per square inch. In addition, if the larger container is in contact with a small one and has a piston area of 10 square inches, it will have a force of 10 pounds to lift a heavy object with a large piston.
For example, floor lifts are used in almost any industry, and as they are called, they are located on the floor - you can see them in the automotive industry, they can lift the building to replace the foundation, using a pump lever to lift things. This type of jack requires a solid foundation for maximum stability, and it can lift huge heights from 2 to 20 tons.
Some of the great inventions, such as hydraulic jacks, are built in a very simple way and follow simple rules, but they do work wonders.
