the equilibrium principle. the equilibrium principle

In this state the net effect of all the forces is nil. A body in equilibrium has no resultant and no couple acting on it. Such a body has no linear or angular acceleration.

Effect of concentration change

It may be either at rest or moving with uniform velocity. Conditions of equilibrium: On a body at equilibrium there is no resultant force and also there is no moment i. Resultant is zero only if the algebraic sum of components along two mutually perpendicular axes is zero. The first two conditions eqiilibrium applicable for concurrent forces and all the equilibrium principle three conditions must be applicable for non-concurrent forces.

Principles of Equilibrium: A few common principles equilibrium are: Two force principle: States that if two forces are in equilibrium they must be equal, opposite and collinear.

the equilibrium principle

Three force principle: States that if three forces are in equilibrium then resultant of any two forces must be equal, opposite and collinear with the third force. Also if three forces are in equilibrium they are always concurrent.

the equilibrium principle

Four force principle: States that if four forces are in equilibrium then resultant of any two forces is equal, opposite and collinear with the resultant of other two forces. Equilibrant Force E : It is defined as a single force which when applied with given forces brings the body in equilibrium.]

One thought on “The equilibrium principle

  1. In my opinion the theme is rather interesting. I suggest you it to discuss here or in PM.
