One advantage is that it results ind a greater, more efficient, and consistent power output. One disadvantage is hydraulic fluid his highly corrosive.

# How hydraulic lift uses pascal's law?

Hydraulic systems use a incompressible fluid, such as oil or water, to transmit forces from one location to another within the fluid. Most aircraft use hydraulics in the braki…ng systems and landing gear. Pneumatic systems use compressible fluid, such as air, in their operation. Some aircraft utilize pneumatic systems for their brakes, landing gear and movement of flaps.Pascal's law states that when there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the container.A container, as shown below, contains a fluid. There is an increase in pressure as the length of the column of liquid increases, due to the increased mass of the fluid above.For example, in the figure below, P3 would be the highest value of the three pressure readings, because it has the highest level of fluid above it.If the above container had an increase in overall pressure, that same added pressure would affect each of the gauges (and the liquid throughout) the same. For example P1, P2, P3 were originally 1, 3, 5 units of pressure, and 5 units of pressure were added to the system, the new readings would be 6, 8, and 10.Applied to a more complex system below, such as a hydraulic car lift, Pascal's law allows forces to be multiplied. The cylinder on the left shows a cross-section area of 1 square inch, while the cylinder on the right shows a cross-section area of 10 square inches. The cylinder on the left has a weight (force) on 1 pound acting downward on the piston, which lowers the fluid 10 inches. As a result of this force, the piston on the right lifts a 10 pound weight a distance of 1 inch.The 1 pound load on the 1 square inch area causes an increase in pressure on the fluid in the system. This pressure is distributed equally throughout and acts on every square inch of the 10 square inch area of the large piston. As a result, the larger piston lifts up a 10 pound weight. The larger the cross-section area of the second piston, the larger the mechanical advantage, and the more weight it lifts. The formulas that relate to this are shown below:P1 = P2 (since the pressures are equal throughout).Since pressure equals force per unit area, then it follows thatF1/A1 = F2/A2It can be shown by substitution that the values shown above are correct, 1 pound / 1 square inches = 10 pounds / 10 square inchesBecause the volume of fluid pushed down on the left side equals the volume of fluid that is lifted up on the right side, the following formula is also true.V1 = V2by substitution,A1 D1 = A2 D2A = cross sectional areaD = the distance movedorA1/A2= D2/D1This system can be thought of as a simple machine (lever), since force is multiplied.The mechanical advantage can be found by rearranging terms in the above equation to (MORE)
