How Hydraulic Machines Work

­From backyard log splitters to the huge machines you see on construction sites, hydraulic equipment is amazing in its strength ­and agility! On any construction site you see hydraulically operated machinery in the form of bulldozers, backhoes, shovels, loaderss, fork lifts and cranes.

Hydraulics operate the control surfaces on any large airplane. You see hydraulics at car service centers lifting the cars so that mechanics can work underneath them, and many elevators are hydraulically operated using the same technique. Even the brakes in your car use hydraulics!

here is an exparamnt and example

look at the picture below . think of an example like a jack hammer it uses air preshur there is 2 types you can have oil orair power. air is louder than oil.

Hydraulic machines are machinery and tools that use liquid fluid power to do simple work. Heavy equipment is a common example.

In this type of machine, hydraulic fluid is transmitted throughout the machine to various hydraulic motors and hydraulic cylinders and which becomes pressurised according to the resistance present. The fluid is controlled directly or automatically by control valves and distributed through hoses and tubes.

The popularity of hydraulic machinery is due to the very large amount of power that can be transferred through small tubes and flexible hoses, and the high power density and wide array of actuators that can make use of this power.
