What are the Three States of Equilibrium


Three States of Equilibrium

 

There are following three states of Equilibrium:

 

  1. First State (Stable Equilibrium)

 

A body at rest is in stable equilibrium if on being displaced, it has the tendency to come back to its initial position.

 

When the centre of gravity of a body i .e. below the point of suspension or support, then body is said to be in stable equilibrium.

 

  1. Second State (Unstable Equilibrium)

 

If a body on displacement topples over and occupies a new position then it is said to be in the state of unstable equilibrium.

 

When the centre of gravity lies above the point of suspension or support, the body is said to be in the state of unstable equilibrium.

 

 

  1. Third State (Neutral Equilibrium)

 

If a body is placed in such state that if it is displaced then neither it topples over nor does it come back to its original position, then such state is called neutral equilibrium.

When the centre of gravity of a body lies at the point of suspension, then the body is said to be in neutral equilibrium.

 

consciousness moves in an ignorant cycle and a person loses a sense of reality, becomes stupid with everyone resulting. The most important thing is to stop thinking, completely block all information, thus consciousness enters into silence, internal energies come into harmony and balance, vital energy is restored, and an inner renewed pure awareness comes. Reading a lot is harmful – Definitely! Solid pluses, minuses only in the flashlight. Useless. It is better to write if there is something.
