The center of buoyancy is the center of volume of displaced water of the hull (of a vessel). Gravity pulls down on a floating object. The fluid it is floating on pushes it up and it floats (assuming it is bouyant). Both gravity and bouyancy (the two forces at work) will have an effective center. The center of gravity is not required to be lower than the center of bouyancy and in general most ship's center of gravity is above the center of bouyancy. The ship will heel until the Metacenter (which is a function of the actual Waterplane area) is at or above the center of gravity. It might be advantageous to look at the center of gravity with respect to the center of bouyancy in ship hull stability and thereby get a better grasp of the particulars. Use the link below to our friends at Wikipedia and look at some diagrams concerning the stability of ships in terms of where the centers of bouyancy and gravity are in relation to each other.
Buoyancy is used for many life examples, submarines, swimmers would like to know about it, and the army would use it. Those are some life examples that of real life that buoyancy would be used! Hope this helps!
Archimedes Principal is the principal for buoyancy
Buoyancy.
The object will float or sink.
Ships, boats etc.
You can change your center of buoyancy by adding weights to a different area.
B=(pb-pt)a
Center of gravity is supposed to act at the centroid of the body. while center of buoyancy is the center of gravity of fluid displaced . so they cant be at single point. if the body is completely submerged and homogenous then both cg and cb will coincide
centre of buoyancy = 1/2 (y) centre of gravity = 1/2 (H)
The center of mass is the point where an object's mass can be considered to be concentrated. The center of buoyancy is the center point of the volume of fluid displaced by an object in a fluid. For floating objects, the center of mass and center of buoyancy coincide.
When the center of buoyancy is directly above the center of gravity a floating object is stable.
A metacentric diagram is a graphical representation of a ship's stability characteristics. It shows the relationship between the center of buoyancy, center of gravity, and the metacentric height. By analyzing this diagram, naval architects can assess the stability of a vessel in different loading conditions.
The two main types of buoyancy are positive buoyancy, which causes an object to float, and negative buoyancy, which causes an object to sink. Another type, neutral buoyancy, occurs when an object neither sinks nor floats but remains suspended in water at a specific depth.
The center of pressure of a submerged body lies below the center of gravity because the pressure increases with depth in a fluid. This leads to a net upward force called buoyancy acting on the submerged body, making it feel lighter and causing it to rotate until the forces are balanced.
Buoyancy
metacentre is above centre of buoyancy to ensure the rightning lever or uprightning moment is in the same direct of the ships heeling that will tend to make the ship upright
Gravity is the force by which a planet or other body draws objects toward its center. Buoyancy is the upward force exerted by a fluid that opposes the weight of an immersed object. Gravity acts on all objects, while buoyancy specifically relates to objects submerged in a fluid.
