A hydraulic system is a type of mechanical system that uses pressurized fluid to transmit and amplify forces. It consists of a pump, a fluid reservoir, and a system of tubes and valves that control the flow of fluid. In a hydraulic system, the pump pressurizes the fluid and pushes it through the system.
