With our understanding of Pascal's principle, we can understand how the principle can be used to make heavy lifting easier, like the hydraulic jack used by the mechanic at the beginning of our lesson.

• ### Pressure and Pascal's Law Flashcards | Quizlet

A hydraulic lift is used to lift a heavy machine that is pushing down on a 3.0m2 piston (A1) with a force (F1) of 4,000N. What force (F2) needs to be exerted on a 0.050m2 piston (A2) to lift the machine?

• ### Pascals principle and hydraulic lift | Physics Forums

Feb 10, 2012· I assume you are referring to the hydraulic lift in post#12. So the situation is that the piston with mass m and area A exerts a downward force on the fluid =mg. In exerting this downward force the piston creates a pressure =mg/A in the fluid.

• ### 14.3 Pascal's Principle and Hydraulics – University ...

Aug 03, 2016· The hydraulic jack is such a hydraulic system. A hydraulic jack is used to lift heavy loads, such as the ones used by auto mechanics to raise an automobile. It consists of an incompressible fluid in a U-tube fitted with a movable piston on each side. ... Pascal's principle applied to hydraulic systems is given by . Significance.

• ### How is Pascal's Law used in a hydraulic lift? by Bri Crosier

How is Pascal's Law used in a hydraulic lift? The hydraulic lift works because of Pascal's law. If force is put on f1 (according to Pascal's Law), the that force should evenly be felt on all points throughout the liquid. Because a2 is a greater area than a1, the force is

• ### Pascal's Principle - ce. T

It is easy to calculate how a hydraulic lift works using the original equation for pressure, P = F/A. Pascal's Principle tells us that the pressure on the right side equals that on the left, so we have P 1 = P 2 F 1 /A 1 = F 2 /A 2 . If A 1 = 10 cm 2 and A 2 = 100 cm 2, then the force F 2 will be 10 times the force F 1

• ### Understanding Pressure Using Pascal's Principle - dummies

Yes, indeed — that's how hydraulic equipment works. By using a small piston at one end and a large piston at the other, you can create huge forces. Backhoes and other hydraulic machines, such as garbage trucks and hydraulic lifts, use Pascal's principle to function.
