Elastic Behavior and Molecular Theory
The elastic behaviour of a material can be explained by the Kinetic Theory of Matter. Since the molecules in a solid are very close to each other, there exist strong attracting forces between them. Thus when force is removed, the attraction forces between the molecules pull them back again and the material is restored to its original shape. Different materials have different elasticity depending on the nature of the material.
Elastic Limit:
The maximum resisting force of a material is called the Elastic Limit of that material.
Nevertheless, I will hope that literate people will download books from there and re-upload them. For example, I have about 40 GB. books with the lion’s share of veterinary and medicine. The rest are mainly in other natural sciences. Everything is not like there is no time to bring them to mind, organize them and put them on whatever file hosting service. I recommend doing something similar to others. Earlier
