Pascal's Law

Pascal's Law states that when pressure is applied to a confined fluid (liquid or gas), this pressure is transmitted evenly throughout the entire fluid and equally in all directions. This means that any change in pressure at one point affects the entire enclosed fluid equally. For example, in a hydraulic system, applying force to a small piston increases pressure that is transferred through the fluid to a larger piston, amplifying the force. This principle is fundamental to understanding how devices like hydraulic brakes and jacks operate efficiently and reliably.
