metacenter การใช้

In 1735 Bouguer sailed with Charles Marie de La Condamine on a metacenter as a measure of ships'stability.
Unfortunately, the spreader bars also make the hammock unsteady since the metacenter of the hammock when sleeping is very high.
The water draft of a large ship has little direct link with its stability because stability depends solely on the respective positions of the metacenter of the hull and the center of gravity.
Because the stability of a ship is largely due to freeboard at high rolling angles, she was given a larger metacentric height ( the vertical distance between the metacenter and the centre of gravity below it ) of around instead of the of the rest of the " Royal Sovereign " s to make her roll less in rough seas.
Metacentre is determined by the ratio between the inertia resistance of the boat and the volume of the boat . ( The inertia resistance is a quantified description of how the waterline width of the boat resists overturning . ) Wide and shallow or narrow and deep hulls have high transverse metacenters ( relative to the keel ), and the opposite have low metacenters; the extreme opposite is shaped like a log or round bottomed boat.
