​Hyraulic system

What is it?

A hydraulic system ​is a compression device that makes

use of external force placed upon a fluid,

create a resulting force.

​

It follows Pascal's Law and invented by ​Joseph Bramah.

Some text here about the topic of discussion

There are many examples out there that uses hydraulic system to make work easier. Such examples are: hydraulic lift, hydraulic jack and hydraulic press.

Open Ended

Describe 2 other examples of the application of hydraulic press.

Pascal's Law

According to Pascal's law, any force applied to a confined fluid (liquid and gas) is transmitted uniformly in all directions throughout the fluid regardless of the shape of the container.

​

The next slide explains how Pascal's Law can be used in a hydraulic press​.

From the previous slide, Pascal's law is the transmission of force throughout a .......?

• Solid

• Liquid

• Gas

• Liquid and gas

Hydraulic principle explained

According to Pascal's Law, as you apply a force (F1) to the piston of an area (A1), the pressure (P) in the confined fluid remains unchanged. This causes a force (F2) to the another piston of an area (A2).
