Pascal's Principle Summary

Hydraulic press is a machine which works on Pascal’s law. It consists of two cylinders of different cross-sectional areas. They are fitted with pistons of cross-sectional areas a and A. The object to be compressed is placed over the piston of large cross-sectional area A. The force F1 is applied on the piston of small cross-sectional area a. The pressure P produced by small piston transmitted equally to large piston and a force F2 acts on A which is much larger than F1.
Formulas

-
Apply pascal’s law, the pressure on large piston of area A will be the same as on small piston.
-
Comparing the above equations, we get:
-

-
Since the ratio is greater than 1, hence the force F2 that acts on the larger piston is greater than the force F1 acting on the smaller piston. Hydraulic systems working in this way are known as force multipliers.
