\n‘Hydraulic brakes’ and ‘Hydraulic lift’ are devices in which fluids are used for transmitting pressure.
\n<\/section>\n
\nThese devices operate based on Pascal’s Principle, which states that pressure applied to an enclosed fluid is transmitted undiminished to every portion of the fluid and the walls of the containing vessel. In hydraulic systems, a small force applied to a small area (piston) creates pressure in the fluid (Pressure = Force\/Area). This pressure is transmitted through the fluid to a larger area (piston), resulting in a larger force output (Force = Pressure * Area). The fluid acts as the medium to transmit this pressure.
\n<\/section>\n
\nWhile force is transmitted and amplified in hydraulic systems, the fundamental principle at play, enabling the transmission and multiplication of force, is the uniform transmission of pressure throughout the fluid. Work done (Force x Distance) is ideally the same at both input and output ends, neglecting energy losses, but the force and distance are traded off (small input force over large distance results in large output force over small distance).
