![]() The handle is moved up and down repeatedly until the load is sufficiently lifted up by the hydraulic fluid flowing buffer tank to the small cylinder. Therefore, we can say that when force is applied, the pressure is exerted throughout the volume and surface of the cylinder. When its handle is pressed down, a valve closes and the small piston forces the fluid through another valve to a larger cylinder which, then, produces a large force to be transmitted to the load. The hydraulic jack consists of two cylinders, a larger and a smaller one and these two cylinders are connected. Hydraulic jacks, which come under the category of a closed container, follow the principle of Pascal’s Law. ![]() The hydraulic lift technology has widespread applications in the industrial, construction, transport sector, etc. When pressure from piston A is transmitted to piston B, piston B lifts the heavy object like big machines, vehicles. The mathematical representation of the Pascal’s Law helps in the determination of pressure which can be exerted on the fluid in the piston so as to create enough force for lifting and moving an object. A narrow cylinder (A) is connected to a wider cylinder (B) fitted with airtight pistons filled with an incompressible fluid. It is based on the principle of equal pressure transmission throughout the fluid. In the case of hydraulic lifts, force applied creates “lift” and “work.” It has a hydraulic apparatus which is used to lift heavy objects. Hydraulic LiftĪ hydraulic lift is versatile in its utility. Let us have a look at some of the examples of Pascal’s Law: 1. The mathematical representation of the law is as follows:į = PA where F=applied force, P=pressure transmitted, and A=cross-sectional area. Therefore, it can rightly be said that since the liquid does not flow, it definitely has equal pressure acting on it at all the points. ![]() However, if we consider that an unequal force is acting on the horizontal bar, in that case, the liquid will have some net force acting on it and it will flow. If we begin to consider that fluid is a horizontal bar with a uniform cross-section and it is in a state of equilibrium, then there will be an equal and balanced force which will be exerted at the two ends. Now, we get to know that pressure is not a vector quantity and, therefore, it can not be assigned any direction. He observed that when a fluid is at rest, the same amount of pressure is applied at all the points which are at the same height. The law was proposed by Blaise Pascal, a French Physicist and Mathematician. Pascal’s Law is applicable to both solids and liquids. Pascal’s Law states that the pressure applied to a fluid in a closed container is transmitted equally to all points in the fluid and act in all directions of the container.
