Mainly, the stability of a body depends upon the base area and height of centre of gravity for a body. Stability of a body increases with base area and decreases with the height of centre of gravity.
There are three types of equilbrium for a body i.e.,
Stable equilbrium:- A body is in stable equilbrium when its position is not disturbed.
Unstable equilbrium:- A body is in unstable equilbrium , if it does not regain its original position after it is being slightly disturbed
Neutral equilbrium:- A body is in neutral equilbrium if it changes its position without change in equilbrium after being disturbed.
The stability principle is mainly used in constructing ship. For that purpose, the base of the ship is made as large as possible and the height of the centre of gravity is made as small as possible to maintain the stability of the ship very high. Due to this reason, even the ship tilts a side but it regains its original position so that the ship is in stable equilbrium.
Another application of stability is person walking on a rope. When a person is walking on a rope by holding a long pole in his hand, he changes the orientation of the pole such that the line of action of the total weight passes through the rope so that he does not fall down.
