Center of mass and rigidity and torsions Physics Forums. The mass of the object (vessel) is equal to the mass of an equivalent volume of water (displacement). When a vessel is in static equilibrium, the center of gravity and buoyancy act on the same vertical line. Buoyancy acts perpendicular to the water line (upwards) at the center of buoyancy. Center of gravity usually lies amidships and near to the water line. Center of buoyancy changes dependant, Explains how balance depends on the position of the center of gravity (or center of mass)..

Case 1 applies a global-X unit load to an arbitrary point, perhaps the center of mass, such that the diaphragm rotates R zx. Case 2 applies a global-Y unit load at the same point, causing rotation R zy . As the aircraft is stable when center of gravity is in the nose and unstable when center of gravity is in the tail, there is a position in the middle where the aircraft is neither stable nor unstable i.e the stability is neutral. This point is called the neutral point. The neutral point is fixed for a particular aerodynamic configuration of the aircraft.

A center of gravity is the one element within a combatantвЂ™s entire structure or system that has the necessary centripetal force to hold that structure together. The position of the centre of gravity of an object affects its stability. The lower the centre of gravity (G) is, the more stable the object. The higher it is the more likely the object is to topple over if it is pushed. Racing cars have really low centres of gravity so that they can corner rapidly without turning over.

Center of gravity of a body is a point where total weight of the body is concentrated. Every body posses a center of gravity and this is irrespective of the body. Its is not necessary that the center of gravity should be within the body, but it may also be situated in space out side the body. Explains how balance depends on the position of the center of gravity (or center of mass).

The centre of gravity (COG) of the human body is a hypothetical point around which the force of gravity appears to act. It is point at which the combined mass of the body appears to be concentrated. Because it is a hypothetical point, the COG need not lie within the physical bounds of an object or The Center of Pressure always tries to follow the Center of Gravity. So, you can see that if your Center of Gravity is closer to your fins than your Center of

As alluded to earlier, the center of gravity is the point at which the body's mass is equally balanced, and this point changes depending on one's position (arms up/down, leaning, turning a somersault, etc). As the aircraft is stable when center of gravity is in the nose and unstable when center of gravity is in the tail, there is a position in the middle where the aircraft is neither stable nor unstable i.e the stability is neutral. This point is called the neutral point. The neutral point is fixed for a particular aerodynamic configuration of the aircraft.

Low stability (high mobility), in contrast, occurs with a small base of support, a high center of gravity, a center of gravity projection near the edge of the base of support, a small body mass, and low friction. Do not rely on this method to give you a center of gravity location that you can use in calculation or for balancing purposes. Accuracy depends on your payload.
