Pascal's+Principle

​


 * Transmitting Pressure in a fluid** **​ : **

- When force is applied to a confined fluid, the change in pressure is transmitted equally to all parts of the fluid (Jones).
 * **What is Pascal's Principle**

- The device consists of two pistons one at each end of a U-shaped tube. A piston is like a stopper that slides up and down in a tube (Jones).
 * **Using Pascal's Principle**

- A hydraulic device works by applying a force to an enclosed fluid (Jones).

- The pressure in any liquid depends on the liquid's depth; the greater the depth, the greater the pressure. Hydraulic systems, include car jacks and many other type of everyday tools

**Hyraulic Systems:**

- A hydraulic system multiplies force by applying the force to a small surface area. The increase in pressure is then transmitted to another part of the confined fluid, which pushes on a larger surface area (Jones).

- Hydraulics is the study of the flow of fluids and how they can be used in machines capable of giving a mechanical advantage. This is possible because of the property of liquids described by Pascal's Principle, which states that the force per unit area (pressure) applied to an enclosed liquid is transmitted without change to every part of it, whatever the shape of its container. ​ - Hydraulic lift systems are used to raise cars off the ground so mechanics can repair them easily(Jones).
