[amp_mcq option1=”vertical upward force through e.g. of body and center line of body” option2=”buoyant force and the center line of body” option3=”mid point between e.g. and center of buoyancy” option4=”all of the above” correct=”option2″]
The correct answer is: B. buoyant force and the center line of body.
Metacenter is the point of intersection of the vertical upward force through the center of gravity of a floating object and the line of action of the buoyant force. It is a measure of the stability of a floating object.
The buoyant force is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. It is equal to the weight of the fluid displaced by the object.
The center of gravity is the point at which the entire weight of an object can be considered to be concentrated. It is located by balancing the object on a knife edge.
The line of action of the buoyant force is the line along which the buoyant force acts. It passes through the center of gravity of the displaced fluid.
The metacenter is located above the center of gravity of a floating object. The higher the metacenter, the more stable the object is. If the metacenter is below the center of gravity, the object is unstable and will capsize.
The metacenter is an important concept in naval architecture and marine engineering. It is used to design ships and boats that are stable and safe to operate.
