Elasticity

What is elasticity? Elasticity is a property in certain substances that when one stretches it repeatedly, it will return to its original shape. However, there is an elasticity limit to every object, or how much stress can be applied to the object without it breaking or forming permanent deformation. When the stress applied to the elastic object is tolerable, it yields to the pressure and restores to its original shape when the stress is released; when the stress becomes too great, and it breaks or forms permanent deformation. The elastic property that allows elastic matter to return to its original shape is called elastic rebound. The elastic rebound and the elasticity directly varies as the temperature. Lots of materials have elasticity; a very good example is an elastomer, or rubber.
Most rubber contains only one kind of molecule. The rubber molecules are interconnected by chemical bonds called springs in a vibrating structure. At a normal state, they are always in a ...
