Relationship between location of the center of the gravity and stability?

Answer 1

If you drop a line straight down from the center of gravity of the bridge and it falls inside the base of the bridge, the bridge is in stable equilibrium; it will balance. If it falls outside the base, it is unstable.

Answer 2

The Center of Gravity(CG) is important for the performance of the airplane in flight. For many aircraft, the CG must be within a small distance and very close to the wing spar and the center of Lift. If the CG is too far forward or backward, then the aircraft has to be trimmed to fly level. When it is trimmed, the extra lift (or negative lift) by the Tail can reduce the total lift of the airplane or result in decreased airspeed due to the attitude of the airplane.
For extreme cases, aircraft have taken off and the cargo load has shifted aft, causing the airplane to pitch its nose up to an extreme angle such that it could not recover or fly level and they have crashed.
i don't no

Answer 3

If the centre of gravity falls outside of the base, it will topple over.

Answer 4

If for example a human stands up straight, his center of gravity is in a certain position. If the human bends down, the center of gravity changes because of the different shape produced.

Answer 5

The relationship between the Location of the centre of gravity and stability is that the higher the centre of gravity then the lower the stability.

Answer 6

geometry of the object

location of the object

material of construction and total mass

state of object - free, floating, suspended etc.

Answer 7

it keeps the plane steady and fly

Answer 8

distance from the pivot and mass distribution
