center of buoyancy
Noun: * (Physics) The center of mass of the immersed part of a ship or other floating object. It is the point through which the total buoyant force (the upward force exerted by the fluid) acts vertically. For an object to be stable in a fluid, this point must align correctly with the center of gravity.
The term "center of buoyancy" is used exclusively in the fields of physics, naval architecture, and engineering to describe a precise, calculable property of a submerged or floating body. * The stability of a ship depends greatly on the relative positions of its center of buoyancy and its center of gravity. * When the ship tilted, its center of buoyancy shifted to the side, creating a righting moment to bring it back upright. * Engineers must calculate the center of buoyancy to design a stable hull.
- Metacenter: A key related concept is the . It is the intersection point of the vertical line through the center of buoyancy of a tilted object and the original vertical centerline. The distance between the center of gravity and the metacenter determines stability.
- Righting Moment: The horizontal distance between the line of action of buoyancy (through the center of buoyancy) and the line of action of gravity creates a that returns a stable vessel to an upright position.
- Centre of buoyancy: The British English spelling variant.
- Centre of flotation: A related but distinct term referring to the center of the waterplane area (the plane where the hull meets the water's surface).
- Buoyancy (n): The upward force exerted by a fluid that opposes the weight of an immersed object.
- Buoyant (adj): Able to float; or cheerful and optimistic (a separate, common meaning).
- Centre of buoyancy (UK variant).
- Center of displacement: A less common but technically accurate synonym, as buoyancy equals the weight of the displaced fluid.
- Center of gravity: The point where the total weight of the body is considered to act.
- Archimedes' principle: The physical law stating that the buoyant force on an object equals the weight of the fluid it displaces, which is fundamental to the concept of the center of buoyancy.
- Hydrostatics: The branch of fluid mechanics that studies fluids at rest, within which the center of buoyancy is analyzed.
