We think and indulged in wonder that some technological progress like a hydraulic jack work. This device, as a lot of other, work on the base of Blaise Pascal's Principle that in a closed container, the pressure at all points is the equal. The hidden thing is easy and has nothing to do with complex mechanisms. We can define the pressure mathematically that is Force divided by Area. It means if you have two joint cylinders one large and one small and apply some force on them the small cylinder shows results in a pressure and the pressure will same on all points and the large cylinder will also under the same pressure.
Hydraulic jacks use that principle and work with the force that the larger container emits and because it has greater area, the produced force is greater as well. It turns out that if there is big difference in the areas of the cylinders used, the potential force output of the bigger one will be much more powerful. Therefore, this device is constructed in a very simple way two connected cylinders and the answer to how it works is leverage. The pressure described above is a result of the following the cylinders are full with fluid under pressure that exert that same pressure through its own volume and against the surface of the cylinders containing it. This compressed fluid is typically oil, because it lubricates the system and is forced to the cylinders with a plunger. As it comes up the liquid goes through a valve pump. As the plunger goes down it sends the liquid to another valve into the cylinder.
That's way Hydraulic jacks can produce great amounts of force while applying a small force to it. If a square inch piston applies a one pound weight to a hydraulic liquid, it will give a pressure of 1 pound per square inch. Moreover if there is a connection between both the large and the small container and a piston area of 10 square inches then it will have the force of 10 pounds to raise a weighted object with the huge piston.
We take example of floor jacks these are used in approximately all industries as there name mentioned these are positioned on floor. These are used in the automobiles industries. They have the force to pick up and replace basis also by using a force arm to raise things. For maximum constancy these types of jack required a hard ground and can raise great amounts of weights goes to 2 and 20 tons.
Some of the great inventions like the hydraulic jacks are built in a very simple way and follow simple rules, but they truly work wonders.
