EQUILIBRIUM: It results when the forces acting upon a body are balanced and the body remains at rest.
Types of equilibrium are
- Stable equilibrium: If the forces acting upon a body at rest tend to restore it to its original position after it has been displaced, the body is said to be in stable equilibrium.
- Unstable equilibrium: If a body is given an initial displacement and the forces acting upon it increase this initial displacement, the body is said to be in unstable equilibrium.
- Neutral equilibrium: If, inspite of displacement of a body, the height and position of its centre of gravity remain the same in relation to the base, the body is said to be in neutral position.
