Question

What is Pascal's law?​

Answer 1

Pascal's law says that pressure applied to an enclosed fluid will be transmitted without a change in magnitude to every point of the fluid and to the walls of the container. The pressure at any point in the fluid is equal in all directions.

Answer 2

Explanation:

Pascal's law says that pressure applied to an enclosed fluid will be transmitted without a change in magnitude to every point of the fluid and to the walls of the container. The pressure at any point in the fluid is equal in all directions.

HISTORY

The principle was first enunciated by the French scientist Blaise Pascal. Illustration of Pascal's principle at work in a hydraulic press. According to Pascal's principle, the original pressure (P1) exerted on the small piston (A1) will produce an equal pressure (P2) on the large piston (A2).

Practical applications

Hydraulic jacks, automobile brakes and even the lift generated on airplane wings can be explained using Pascal's principle. Pascal's principle is based on the idea that fluids at rest are incompressible, allowing very large forces to be transmitted with the application of a smaller force.
