Acronym of PA

( Pascal ) In physics, the pressure in this way is defined : P=F/A, which P the pressure, F the force exerted on a surface, and A surface area is F on its impact . Obviously, by taking Newton for Force and square meters for area, etc. pressure for Newton on a square meter will define . The YK direction respect to Scientist, Physicist, etc., called the Pascal was named . Mathematical relationships Pascal with other physical, below . The Pascal (abbreviation Pa), in physics, unit of pressure and is equal to the pressure of one Newton on a square meter.One of the most important features of the pressure fluids, it can be that if some of the liquid within the container enclosed under pressure to put, or in other words, to the pressure we pressure from us, without any weak or low, and shortcomings to all parts of the water looks like and even to the walls of the container pass the time when the principle of Pascal is said to be.In the everyday life of us humans, from many that we use these devices based on the principle of Pascal designed and built.For example, (car brake)so that pressing the brake pedal by the driver the pressure exerted from the feet of the driver to the pedal via brake fluid, which is pre-spilled to the Pistons and brake shoes, and padding, can be passed.The way that the hot shoe to the bowl rear brake force entered, they can eventually force the padding to the page attached to the front wheels enter the speed of the car decrease, and after a moments stops.
