Shear ForcesNormal Forces(pressure)where F is a force normal to area APankaj ChhabraFluid mechanicsA womans high heels sink into the soft ground, but the larger shoes of the much bigger man do not.

Pressure = force/area1 Pa = 1 N/m2Pankaj ChhabraFluid mechanicsPressure & Pascals Principle

Pressure applied to any part of an enclosed fluid is transmitted undimished to every point of the fluid and to the walls of the containerEach face feels same force

Any change in the pressure of a fluid is transmitted uniformly in all directions throughout the fluid.Pankaj ChhabraFluid mechanics4

Pascal lawPankaj ChhabraFluid mechanics5A small force F1 applied to a piston with a small area produces a much larger force F2 on the larger piston. This allows a hydraulic jack to lift heavy objects.
