Hydraulics is a branch of science and engineering that deals with the study of liquids in motion. It explores the principles of fluid mechanics, particularly how liquids behave under pressure and how their energy can be harnessed to perform work. The term "hydraulics" itself originates from the Greek words "hydor" meaning water and "aulos" meaning pipe.

In practical applications, hydraulics often refers to systems that use pressurized liquid, typically oil, to transmit power. These systems consist of several key components: a reservoir to hold the fluid, a pump to generate flow and pressure, control valves to direct the fluid, and actuators (like cylinders or motors) that convert hydraulic energy into mechanical motion. The incompressible nature of liquids makes them ideal for transferring force efficiently and precisely.

Hydraulic systems are widely used across various industries. They are found in heavy machinery such as excavators and cranes, where they provide the immense force needed for lifting and digging. Automobiles utilize hydraulics in their braking systems and power steering. Manufacturing processes often employ hydraulic presses for shaping materials, and hydraulic lifts are common for moving people or goods. The reliability, power density, and controllability offered by hydraulics make them indispensable in many modern technologies.
