Hydraulic systems use water or other liquids to deliver forces where they are needed. The shovel on the front of a bulldozer is moved by hydraulics. The long arm and bucket of a digger is powered using a hydraulic system. The brakes on a train and the jack a mechanic would use to lift up a car both use hydraulics too.
