* Stability of floating bodies. A body is in a Stable equillibrium it It returns to its origional position After being slightly displaced. Newthd Pas.tion if the object remains in the New position After being slightly dis placed A body is in an unstable equillibrium if it continuous to move in the Direction of the displacement. #Stability of floating obs * if the cents of Buoyancy is defined as the centre of the gravity of the Displaced fluid then the stability af a floating object wil depend on whether a righting or over turning moment is develoged when the centre of gravity o and the centre of buoyancy move out of vertical alignment dul to the shifting of the position of the latter. The centre of buoyancy moves belange if a floating body tips. the shape of the displaced liquid changes. in stable condition the forces of Buoyancy thrust and the weight are equed and in line. When a body has been tipped over and the buoyancy has a New position is while G unchanged The vertical though the New centre of buoyancy cuts the drigsonal line, which is stil passing though I at M apoint Known is the metacente, in this case M lies above G, and Stability exists.
