Advantages & Disadvantages of Hydraulic Systems | Sciencing

Apr 24, 2017 ... Hydraulic systems work because of Pascal's law, which states that an increase of pressure in any part of a confined fluid causes an equal increase of pressure throughout the container. If you apply a force to one part of a hydraulic system, it travels through the hydraulic fluid to the rest of the system.
