How do hydraulics increase force?

Hydraulic systems can increase or decrease the force applied to them. To make the force larger, the pressure is applied to a larger area. For example, if a 100-N force is applied to the left cylinder in Figure and the right cylinder has an area five times greater, then the output force is 500 N.

What creates hydraulic pressure?

In a hydraulic system, pressure is usually created by restricting the flow of the fluid, or by gravity.
