Pascal Principle of Transmission of Fluid Pressure

The Peterborough Hydraulic Canal, opened in July 9, 1904, is the biggest lift lock in the world. This lift uses the principle of Pascal to move up and down, and let boats go through the center.

Pascal's law states that when there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the container.

This principle is well know to be used in aircraft hydraulics for the landing gear. Pascal was a French scientist, who studied math and physics. Atmospheric pressure, conic section, and the principle of hydrostatics, were also part of his studies. There were several other scientist afrter Pascal that continued the studied of hydraulics. For example, Bernoilli, Froud, and Franklin continued the study of hydraulics.

Hydraulics are machines that we use everyday. The invention of hydraulics helped change the way we do things. Without the invention od hydraulics the way of creating a car would of been difficult to accomplish. Hydraulics deal with the mechanical properties of liquids. Hydraulics are used for the generation, control, and transmission of power by the pressure of liquids.

Different types of hydraulic machines have been created. For example, there is the hydraulic lift, the hydraulic brake, the hydraulic water pump, and other that we use in our everyday lifes.

ELA Component

In this presentation I will demonstrate to you the way I built the wooden Hydraulic- Lift. This lift will demonstrate Pascals Principle. The force applied to the end of one syringe will create pressure in the fluid, then cause the movement of the fluid to the other syringe and finally moving the other end of the syringe. This method is a basic understanding of real life machines like elevator and hydraulic brakes.

As I went building these lift, I kept track on how different there purpose and their way of working worked. In total, I created four different hydraulic machines. A Hydraulic Brake, a Hydrualic Elevator, a Hydraulic Strawberry Lift, and a Hydrualic Scissor Lift. These machines taught me how everyday machine work and how easy it is to understand their way of working.

Through out the experiment I kept a journal of my designs, my materials, and my advancements. Since I discovered that there were many different types of hydraulic machines I picked the four I mentioned before. These different machines took different designs and different purposes. It took me alot of patience to built all of the machines. Pascal's designs and methods helped me understand the machines functions and also gave me ideas on how to make my machines better.
