🔴 PHY103. ELASTICITY
*ELASTICITY* Elasticity is the ability of a body to resist a distorting influence and to return to its original size and shape when that influence or force is removed Solid objects will deform when adequate loads are applied to them; if the material is elastic, the object will return to its initial shape and size after removal Moving on, the physical reasons for elastic behavior can be quite different for different materials. In metals, the atomic lattice changes size and shape when forces are applied (energy is added to the system). But for rubbers and other polymers, elasticity is caused by the stretching of polymer chains when forces are applied. Let's look into Hooke's law *HOOKE'S LAW* Hooke's law states that the force required to deform elastic objects should be directly proportional to the distance of deformation, regardless of how large that distance becomes This is known as perfect elasticity, in which a given object ...
