Equilibriumand types of equilibrium

 Equilibrium:

 When does not have any acceleration neither linear nor angular, it is said to be

equilibrium. (A chair lift hanging on supporting ropes).

 Two types of Equilibrium:

 Static and Dynamic Equilibrium.

 Static Equilibrium: When a body is at rest is called static equilibrium. Any body which is at

(earth) rest is called equilibrium.

 A wall hanging, building and bridge are examples of static equilibrium.

 Dynamic Equilibrium: When a body having constant velocity is called dynamic equilibrium.

 A body does not have acceleration neither linear nor angular is said to be dynamic

equilibrium.

 The rotation of earth is dynamic equilibrium.
