__**Pascal's Principle **__
 * Blaise Pascal was a French born, 1600's mathematician that developed a principle to explain how pressure is transmitted throughout a fluid. All fluids exert pressure on everything they touch, especially if the fluid is confined in a certain area. Not only that but they also exert the same amount of pressure throughout the entire surface and fluid. It was Pascal who discovered this and would turn this into his own concept. So when a force is applied to a fluid, the pressure is exerted to every part of the fluid. For example,[[image:water_bottle.jpg width="232" height="201" align="left"]] if you were to have a full bottle of water and squeeze it, the water's pressure would increase and be inherited to every part of the fluid (Jones). Because Pressure = Force/Area, the more Force there is in the bottle, the greater the pressure is between the fluid and bottle. While if the bottle isn't full completley, there would be less presure becuase when you squeeze it, the water would rush to where there pressure isn't. **

__**What Are Hydraulic Systems? **__  __**Applying with Hydraulics and Others **__ ** Imagine you are using a Simple Hydraulic System like the one shown here. The tube on on the left has a diameter of 3 sq ft. while the one on the right has a diameter of 6 sq ft. Both sides have about the same amount of fluid. Then you apply a force of 200 Newtons on the left tube. The presure is too much in the left tube to hold, so its forced to travel to the right tube. Now the larger tube has a greater force becasue the fluid in the right tube is increased. Now the right tube has a force of 1200 Newtons becasue 6 sq ft. multiplied by the 200 newtons of force equals that many Newtons. Some other examples of everyday things that use Pascal's Principle are lifing ladders on a firetuck and how star fishes use their water vascular system to move around (Jones). **
 * These devices are simply designed to show how Pascal's principle works. What they do is multiply a fluid's force by first applying a fluid to a small area. Then a greater force is put upon that small area, forcing all that pressure inside to move elsewhere. So the pressure travels now to an area with a larger surface area. As the pressure enters, the force is multiplied becuase that same pressure from before plus the force before it, now has more area to cover, which increases the force (Jones). **
