Elastic materials can regain their original shape and size after the removal of an applied force. This property allows them to undergo reversible deformation without permanent change. Elasticity is crucial in various applications such as springs and rubber bands where materials must withstand forces while maintaining their structural integrity.
Class 11 Physics Chapter 8 focuses on the mechanical properties of solids including stress strain and elasticity. It explores how materials deform under various forces and return to their original shape. Key concepts include Hooke’s law types of stress and strain and the significance of different moduli of elasticity in material behavior.
Elastic fatigue is a condition in which a material loses its elastic properties slowly over time as it experiences repeated or cyclic loading and unloading. Continuous cycles of stress cause the material to lose its elastic recovery properties, thus failing to return to its original shape. Elastic fatigue is very important in engineering and in material selection, especially when it comes to components in bridges, vehicles, and machinery that are subject to fluctuating loads.
