Definition of Elasticity

“The tendency of a material to return to its original dimension after the deforming stress has been removed is known as elasticity.”

If we apply a force to a body, it is stretched. When the applied force is removing, the body returns to its original shape. The phenomenon of turning back to its original shape is called Elasticity.

the rule of good form was to have a small library or at least a collection of books at home. I hope that literate people who collect books have not yet died out, but already on your computer or hard drives. Most likely, it is also illegal to preserve knowledge. Alas, such are our laws, far from humanism and common sense. This is not only about knowledge. Another problem is that many people do not know the laws (what is allowed and what is not), including in relation to copyright.
