Buoyancy -
When a body is either wholly or partially immersed in a fluid, the hydrostatic lift due to the net vertical component of the hydrostatic pressure forces experienced by the body is called the “Buoyant Force” and the phenomenon is called “Buoyancy”.
The Center of Buoyancy is a point through which the force of buoyancy is supposed to act.
When a body is submerged in a liquid (or a fluid), the equilibrium requires that the weight of the body acting through its Center of Gravity should be co-linear with the Buoyancy Force acting through the Center of Buoyancy.
If the Body is Not Homogeneous in its distribution of mass over the entire volume, the location of the Center of Gravity (G) does not coincide with the Center of Volume (B).
Depending upon the relative locations of (G) and (B), the submerged body attains different states of equilibrium: Stable, Unstable, and Neutral.
Stable Equilibrium:
(G) is located below (B).
A body is given a small angular displacement and then released, returns to its original position by retaining the original vertical axis as vertical because of the restoring couple produced by the action of the Buoyant Force and the Weight.
Unstable Equilibrium:
(G) is located above (B).
Any disturbance from the equilibrium position will create a destroying couple that will turn the body away from the original position.
Neutral Equilibrium:
(G) and (B) coincide.
The body will always assume the same position in which it is placed. A body having a small displacement and then released, neither returns to the original position nor increases its displacement- It will simply adapt to the new position.
