Elasticity
Elasticity is the property of materials that allows them to return to their original shape after being deformed by stress, such as stretching or compressing. In continuum mechanics, elasticity describes how materials respond to external forces while maintaining their structural integrity. For example, when you stretch a rubber band, it extends but returns to its initial form once released. This behavior is crucial in various applications, ensuring that structures and components can withstand forces without permanent deformation, which is essential for stability and functionality in engineering and everyday materials.

Elasticity refers to how much something responds to changes in conditions. In economics, for instance, it describes how the demand for a product changes when its price changes. If a small price change leads to a large change in demand, the product is deemed elastic. Conversely, if demand changes little with price alterations, it’s inelastic. This concept applies beyond economics; in physics, elasticity measures how materials stretch or compress. Essentially, elasticity gauges responsiveness, whether in markets or materials, highlighting how sensitive a system is to changes in its environment or circumstances.
