How does Pascal's principle relate to hydraulic lifts? Hydraulic lifts use Pascal's principle to amplify force. Pascal's principle tells us that pressure is transmitted equally throughout a static fluid. A small force exerted on a small area over a large distance is translated into a large force exerted on a large area over a small distance in a device like a car lift.
Pascalâs principle states that a change in pressure at any given point in an enclosed fluid is transmitted equally and uniform in all directions throughout the fluid, ÎP = Ïg(Îh). A fluid is any substance that assumes the shape of its container (liquids and gases are fluids). Pascalâs principle is used in many different applications; such as siphoning, hydraulic jacks, braking systems in automobiles, water towers, and dams. Even scuba divers must understand this principle. The visual often used is a 2-liter bottle and by squeezing the bottle pressure is applied at one point in the fluid. The picture will show magnitude arrows to help visualize this concept. This lab will allow for the students to actually see quantitative and qualitative results when a pressure ...
