Archimedes' principle (also spelled Archimedes's principle) states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces. Archimedes' principle is a law of physics fundamental to fluid mechanics. It was … See more In On Floating Bodies, Archimedes suggested that (c. 246 BC): Any object, totally or partially immersed in a fluid or liquid, is buoyed up by a force equal to the weight of the fluid displaced by the object. See more The equation to calculate the pressure inside a fluid in equilibrium is: $${\displaystyle \mathbf {f} +\operatorname {div} \,\sigma =0}$$ where f is the force density exerted by some outer field on the fluid, and σ is the Cauchy stress tensor. … See more Archimedes' principle shows the buoyant force and displacement of fluid.
