So Pascal's Principle says that the pressure, F divided by A, is the same when transmitted through a fluid. So F1 divided by A1 is equal to F2 divided by A2F1/A1= F2/A2. This means that if you push with a small force on a small area, this can lead to the application of a large force on a large area. This is surprisingly useful; one of the applications of Pascal's principle applied today in maritime technology is the hydraulic system nowadays. Hydraulics is defined as the branch of science and technology concerned with the transportation of liquids through pipes and channels, particularly as a source of mechanical force or control. And this is by far the most common application of Pascal's principle. There are many, many uses of the principle, but almost all of them boil down to hydraulics. Robotic arms are most commonly used in maritime technology to lift heavy loads
