Hydraulic Systems**
 * Theme 2: Instruments & Machines


 * What is it and how does it work? **
 * The Hydraulic System** is a mechanical appliance that is controlled by pressure. The pressure is transmitted when a liquid is forced through a small tube. In the process, force that is applied at one point, is transmitted to another point using an oil like fluid. That force is always increasing. The picture below illustrates an Hydraulic System in a Piston Water Gun:



The Piston gun consists of water inside of it. When the user applies physical force to the piston's handle (pushing it forward), the water from inside the piston is forced out the nuzzle. The concept is known as Hydraulic multiplication. The fluid inside the object is transfered from one to another by force. The force is always increasing.



In the picture above, two red pistons are fitted into two glass cylinders that are attached to another large cylinder filled wit oil. The two cylinders are connected to each other by the other large cylinder. If you apply force to one piston by pushing downward, the force would transfer to the second piston. The oil combined with the hydraulic system causes an effect in which the other piston pushes upward.

**What is it used for?**

The Hydraulic System is used in many ways, particularly in machinery. It is used in large industries for production, such as automobile or heavy-duty machinery production. It is also used in heavy-duty construction work, such as bulldozers, folk lifts, trucks, cranes, etc. Aircrafts also uses an hydraulic system. A hydraulic system is placed in the wing and wheel of most large aircrafts for landing. Even submarines also uses a hydraulic system to operate in water.
