Metacenter | Definition & Facts | Britannica
网页metacentre, in fluid mechanics, the theoretical point at which an imaginary vertical line passing through the centre of buoyancy and centre of gravity intersects the imaginary vertical line through a new centre of buoyancy created when the body is displaced, or tipped, in the water, however little.
Metacentric height - Wikipedia
网页The metacentric height (GM) is a measurement of the initial static stability of a floating body [1]. It is calculated as the distance between the centre of gravity of a ship and its metacentre. A larger metacentric height implies greater initial stability against overturning.
穩心高度 - 维基百科，自由的百科全书
网页穩心(metacentre)是判斷一個浮水面的物體的穩定度的重要指標，用以判斷物體是否可以穩定的浮在水面上而不致於翻覆。 穩心高度(metacentric height)是穩心到浮體的重心的距離。
Naval architecture - Metacentric Stability, Buoyancy, Stability
网页For small angles of inclination, say less than 10°, the verticals through the shifted centres of buoyancy intersect the ship centreline at or close to a point M, called the metacentre. The stability provided by the action described is therefore called metacentric stability.
Metacenter Definition | Fluid Mechanics - YouTube
网页2013年9月10日 · The video demonstrates the concept of Metacenter and Metacentric Height. It also explains the importance of this concept for the stability of Floating Bodies like ships and boats. The video is a ...
Metacentre - Explanation, Formula, Free Surface Effect and FAQs
网页3 天之前 · In fluid dynamics, metacentre is the theoretical point where an imaginary vertical line passing through the centre of buoyancy and centre of gravity overlaps an unreal vertical line passing through a separate centre of buoyancy produced whenever the body is relocated, or tipped, throughout the water, however slightly.

网页2011年9月30日 · A Pontoon measuring 20ft.by 12ft. and 4ft deep, weighs 12 tons. It carries a load of 8 tons. The Pontoon sits in sea water with a density of 64 lb/cu. ft. Find it's metacentric height and establish the angular tilt which will result if the load is moved by one ft. sideways. Workings.
Metacentre and Metacentric Height - Mechanical Engineering
网页The Metacentre may be defined as a point about which a floating body starts oscillating, when given a small angular displacement. It is denoted by M. The metacentric height is the distance between the centre of gravity (G) of the floating body and the metacentre (M).
4.6.1.2: Metacentric Height, \(\overline{GM}\), Measurement
网页The metacentric height can be measured by finding the change in the angle when a weight is moved on the floating body. Moving the weight, T T a distance, d d then the moment created is. Mweight = Td (4.6.1.2.1) (4.6.1.2.1) M w e …
