Elasticity Theory
Elasticity theory refers to how materials respond to applied forces. When a force is applied, materials can either deform (stretch, compress, or twist) and eventually return to their original shape (elastic behavior) or permanently change shape (plastic behavior). Elasticity is crucial for understanding the mechanical properties of materials, from rubber bands stretching under tension to the way buildings sway during an earthquake. The degree to which a material can return to its original shape depends on its properties, measured as elasticity, allowing engineers and scientists to design safer structures and products.

Elasticity theory describes how materials respond to forces by deforming and returning to their original shape when the forces are removed. Think of a rubber band: when stretched, it elongates, but when you let go, it snaps back. This principle applies not just to rubber but to many materials, highlighting their ability to absorb and release energy. In broader contexts, such as economics or environmental science, elasticity can refer to how demand or supply reacts to changes, such as price fluctuations or resource availability, illustrating the responsiveness of systems to external changes.
