www.maritimenz.govt.nzbuoyancy may be considered to act. (The force of) buoyancy always acts vertically upwards. Metacentre (M) is a point in space where the vertical line upwards through the centre of buoyancy (B) of the ‘inclined’ vessel cuts through the vertical line upwards through the centre of buoyancy (B) of the ‘upright’ vessel. Metacentric height (GM)
COURSE OBJECTIVES CHAPTER 4 4. STABILITY
www.usna.edubuoyancy is located at the centroid of the underwater volume of the ship. When the ship is heeled over by an external moment the underwater shape changes and thus the centroid moves. Where the center of buoyancy moves with respect to the center of gravity defines the stability characteristics of the ship as the ship is heeled over.

www.me.unm.edu10.7. Stability of horizontal layers T = T 1 T = T 2 x y y = h T 1 < T 2 (hot above cold) – stable (and stably stratified) horizontal thermal layer, heat transfer – by conduction only T 1 > T 2 (cold above hot) – for some DT, unstable stratification leads to convection? Buoyancy

The application of force of Buoyancy is applied on submarines. Water is filled in containers and weight becomes greater thank force of buoyancy and sub-marine sinks.
Buoyancy and stability - gatech.edu
www.cns.gatech.eduBuoyancy and stability “Buoy” mostly pronounced “booe”, probably of Germanic origin. A tethered floating object used to mark a location in the sea. Fishes, whales, submarines, balloons and airships all owe their ability to float to buoyancy, the lifting power of water and air. The understanding of the physics of buoyancy goes back as far
STABILITY OF FLOATING BODIES - Western University
www.eng.uwo.ca(2) To assess stability, first find the location of the centre of gravity G of the body. (3) Then, find the location of the centre of buoyancy B (centroid of displaced volume). For a regularly shaped body this will be at half the height of the immersed portion of the body. (4) Calculate the distance GB. (5) Calculate MB, using MB = I / VS. Note ...
