Mechanical component used for construction of EXO items.
Hydraulics is a topic in science that deals with the mechanical properties of liquids. The concept behind hydraulics is pretty simple: force that is applied at one point is transmitted to another point using an incompressible liquid (or fluid). They have advantage over pneumatic or electrical systems as they are suited for high-force applications and are not very expensive.
From a simple water pistol, to car brakes, heavy machinery, amusement park rides, elevators, airplanes and even your office chair, hydraulic systems are present in everyday life.
