Particularly for applications that require precise control of large forces and smoothmotion, fluid power can deliver significant benefits. However, that means selecting the right hydraulic-system elements and tuning the motion controller for optimal performance.

The science behind hydraulics is called Pascal’s principle. Essentially, because the liquid in the pipe is incompressible, the pressure must stay constant all the way through it, even when you’re pushing it hard at one end or the other. Now pressure isdefined as the force acting per unit of area.

Equipment such as cranes, forklifts, jacks, pumps and fall arrest safety harnessesuse hydraulics to lift and lower objects. Airplanes. They use hydraulic mechanisms to operate their control panels. … Some types of elevators use a hydraulicmechanism to power the elevator car’s movement and make them stop when needed.
