The floating body is bottom-heavy and thus the center of gravity G is directly below the center of buoyancy B, the body is always stable. Stability Of Submerged And Floating Bodies Show the submerged bodies for stable, neutrally stable, and unstable as in figure (1). Stability of Immersed and Floating Bodies. Note: It is a condition for stable equilibrium that M remains higher than G. A floating body is UNSTABLE if, when it is displaced, it moves to a new equilibrium. A floating body is UNSTABLE if, when it is displaced, it moves to a new equilibrium. Stability of Floating Bodies 1 FLUID MECHANICS 8 October 17, 2016. For the untilted body the point G is the centre of gravity of the body where the body weight, W, acts. Stability of floating body depends on its metacentric height. After tilting is the new water line and the angle of Tilt is. The Stability Of Partially Submerged Bodies. This has been used by man for about 2200 years, for the problem of general floatation and naval architectural design. Stability of Floating Bodies: When a body floats, it is subjected to two parallel forces, they are:

Metacentre of a floating body is defined as the point of intersection of the centre line of cross section containing the centre of gravity and centre of buoyancy with the vertical line through new centre of buoyancy due to … A floating body is UNSTABLE if, when it is displaced, it moves to a new equilibrium. H2 Stability of a Floating Body TecQuipment Ltd 3 User Guide or in the limit: (4) The matacentric height may thus be determined by measuring knowing ω and W. Quite apart from experimental determinations, BM may be calculated from the mensuration of the pontoon and the volume of liquid which it displaces. Consider a floating body tilted by an angle , as shown below.

For the untilted body the point G is the centre of gravity of the body where the body weight, W, acts. The Rotational Stability Criteria for Floating Bodies. Stability becomes an important consideration when floating bodies such as a boat or ferry is designed. Archimedes principle is applicable to bodies floating or immersed in a liquid. We say that a body is in stable equilibrium if it is able to return to its position when slightly disturbed. Figure (a) demonstrates the body is steady because of the heavy base, in this way point G is straightforwardly beneath point B. ﻿STABILITY OF FLOATING BODIES (White pp 92 – 95) A floating body is STABLE if, when it is displaced, it returns to equilibrium. is the c. of g., is the c. of b. and the line is the original water surface. stability of floating bodies (white pp 92 – 95) A floating body is STABLE if, when it is displaced, it returns to equilibrium. It is an obvious requirement that a floating body such as a boat does not topple when slightly disturbed.

But unlike immersed bodies, a floating body may still be stable when G is directly above B as shown before. ﻿STABILITY OF FLOATING BODIES (White pp 92 – 95) A floating body is STABLE if, when it is displaced, it returns to equilibrium. Exercise A Objective To locate the position of the Metacentre (M) of a floating body, by determining its distance from the centre of gravity (G); this distance (GM) is known as the Metacentric Height. A floating body is UNSTABLE if, when it is displaced, it moves to a new equilibrium. Consider a floating body tilted by an angle , as shown below. ﻿STABILITY OF FLOATING BODIES (White pp 92 – 95) A floating body is STABLE if, when it is displaced, it returns to equilibrium. remains in the same position relative to the ship but the Centre of Buoyancy moves to . Consider a floating body tilted by an angle , as shown below.
