linear elasticity

Linear elasticity is a property of materials that describes how they deform when force is applied. When a force is applied to an elastic material, it stretches or compresses proportionally to the amount of force, up to a certain limit. This means if you double the force, it will double the deformation. Once the force exceeds this limit, the material may permanently deform or break. Examples include rubber bands and metal springs, which return to their original shape after the force is removed, as long as they haven't been over-stretched or damaged.
