Normal Force in Brakes and Dynamometers Formulas

Normal Force is the force exerted by a surface against an object that is in contact with it, usually perpendicular to the surface. And is denoted by Fn. Normal Force is usually measured using the Newton for Force. Note that the value of Normal Force is always negative.
