Julius Sumner Miller: Lesson 13 - Archimedes' Principle
If a body is submerged in a fluid - a liquid or a gas - the body is buoyed up -lifted up - by a force equal to the weight of the fluid displaced. This is the Classic Principle of Archimedes. We show an array of DEMONSTRATIONS bearing on this Principle. A - We weigh a body on a spr
