Practical Applications

Hydraulics and Fluid Pressure in Technology

Moving the World with Fluids

Hydraulic systems use the principles of fluid pressure to do work. By confining fluids in tubes and pistons, we can lift heavy loads, control vehicles, and even operate amusement park rides.

How It Works

When a force is applied to a fluid in a closed system, the pressure is transmitted equally in all directions (Pascal’s Principle). This makes it possible to multiply force and achieve big results with little effort.

Uses Around Us

Hydraulics are found in car brakes, construction equipment, and even dental chairs.

Examples

  • A car’s hydraulic brakes allow a small pedal force to stop a heavy vehicle.

  • An excavator uses hydraulics to lift tons of dirt with ease.
