### Archimedes' Principle A statue of Archimedes in a bathtub demonstrates the principle of the buoyant force. could make a trade-off between force and distance using a lever. . to help them dive and resurface, it also explains the reason why some. Density and Archimedes' Principle Page Page has been visited times since the difference between the two masses (in grams) will equal (almost exactly) the. Archimedes' principle, physical law of buoyancy, discovered by the ancient Greek mathematician What is Archimedes' principle used for?.

Determination of density by direct measurement of volume. The object you have is a cube of metal. The mass of the cube can be found by weighing it. Then the density can be determined by dividing the mass by the volume.

Weigh your cube on the electronic scale. Record your mass below. Measure the edge of the cube in centimeters with your plastic ruler.

Record the length below. Record the volume below. Record the density below. Archimedes took one mass of gold and one of silver, both equal in weight to the crown.

He filled a vessel to the brim with water, put the silver in, and found how much water the silver displaced.

He refilled the vessel and put the gold in. The gold displaced less water than the silver. He then put the crown in and found that it displaced more water than the gold and so was mixed with silver.

If the body is completely submerged, the volume of fluid displaced is equal to the volume of the body. A floating object displaces a weight of fluid equal to its own weight. Every ship, submarine, and dirigible must be designed to displace a weight of fluid at least equal to its own weight. A 10,ton ship's hull must be built wide enough, long enough and deep enough to displace 10, tons of water and still have some hull above the water to prevent it from sinking. It needs extra hull to fight waves that would otherwise fill it and, by increasing its mass, cause it to submerge. The same is true for vessels in air: If it displaces more, it rises; if it displaces less, it falls.

## Archimedes' principle

If the dirigible displaces exactly its weight, it hovers at a constant altitude. While they are related to it, the principle of flotation and the concept that a submerged object displaces a volume of fluid equal to its own volume are not Archimedes' principle.

Archimedes' principle, as stated above, equates the buoyant force to the weight of the fluid displaced. One common point of confusion[ by whom?
