Pascal’s Law Demonstration wooden frame

Pascal’s Law Demonstration (also Pascal’s principle or the principle of transmission of fluid-pressure) is a principle in fluid mechanics that states that a pressure change occurring anywhere in a confined incompressible fluid is transmitted throughout the fluid such that the same change occurs everywhere.

To understand pascal’s law by applying force on a 50 ml large and 10 ml small piston, students will experience the mechanical advantage of one over the other.

Hydraulic press is a great way to show Pascal’s Law in operation. Students will understand mechanical advantage when they use this system of connected pistons. Apply force to one syringe-type pisto 10 ml to make the liquid rise in the other 50 ml, recreating the concept behind such everyday items as power steering, shock absorbers, hydraulic jacks etc.
