Understanding the Precept of Buoyancy
Buoyancy, in physics, is the upward power exerted by a fluid that opposes the load of {a partially} or totally immersed object. This upward power is the same as the load of the fluid displaced by the article and acts on the middle of buoyancy, which is positioned on the centroid of the displaced fluid.
Archimedes’ Precept
The precept of buoyancy was first formulated by the Greek mathematician and inventor Archimedes within the third century BC. Archimedes’ precept states that an object immersed in a fluid is buoyed up by a power equal to the load of the fluid displaced by the article. This precept could be expressed mathematically as follows:
“`
Buoyant power = Weight of displaced fluid
“`
The burden of the displaced fluid will depend on the next elements:
