Flotation Principle and Explanation – Archimedes

The Archimedes' principle states that any object, wholly or partially immersed in a fluid, experiences an upward force equal to the weight of the fluid displaced by it. Here the term 'fluid' refers to all liquids and gases. For an object that is completely submerged in a fluid, the weight of the fluid displaced by it is less than its own we…

The pressure in flotation tires should not be much higher than the inflation pressure of tractor tires. Keep in mind that while a driven tire actively works against the "bulldozing effect" by rotating, a non-driven tire needs to be turned by outer forces. With deeper track depth and small tires, the "bulldozing effect" becomes more and ...

Floatation: Learn its Principle, Laws, Condition and Applications

The principle of floatation is stated by Archimedes. The concept of flotation was initially articulated by the ancient Greek scientist Archimedes. He asserts that everything submerged in a liquid experiences an upward force, which enables a body to float if it expels water equal to its own weight.

Hydrostatic Pressure

We know that matter in all states exerts pressure. Liquids and gases exert equal pressure on all sides of a container. The normal force exerted by a liquid per unit area of the surface in contact is called hydrostatic pressure or pressure of the liquid. In this article, let us discuss hydrostatic pressure in detail.
