[amp_mcq option1=”centroid of the displaced volume of fluid” option2=”center of pressure of displaced volume” option3=”e.g. of floating body” option4=”does not exist” correct=”option1″]
The correct answer is: A. centroid of the displaced volume of fluid
The center of buoyancy is the point at which the buoyant force acts on a body. It is located at the centroid of the displaced volume of fluid. The centroid is the point at which the entire weight of the displaced fluid would balance.
The center of pressure is the point at which the total pressure of a fluid acts on a surface. It is located at the centroid of the wetted area of the surface.
The center of gravity is the point at which the entire weight of a body would balance. It is located at the centroid of the entire volume of the body.
The center of buoyancy and the center of gravity do not always coincide. For example, a ship’s center of buoyancy is located below its center of gravity, which causes the ship to heel over when it is loaded.
