AS DEFORMATION AND ELASTICITY OF MATTERS YOUNGS MODULUS

Deformation is the change in the shape or size of a body when an external force is applied. When you pull or compress an object, it stretches, compresses, or bends — this is deformation. If the object returns to its original shape after removing the force, the deformation is elastic. If it does not return completely, the deformation is plastic (permanent). Elasticity is the property of a material that enables it to regain its original shape and size after the deforming force is removed. Example: A rubber band or a spring. The measure of elasticity depends on how resistant a material is to deformation. Stress and Strain Before defining Young’s modulus, we must understand stress and strain. 1. Stress (σ): The force per uni t area applied to a body.Deformation is the change in the shape or size of a body when an external force is applied.

Stress (σ): The force per unit area applied to a body. Young’s modulus is a measure of the stiffness or rigidity of a material. It is the ratio of stress to strain in the region where Hooke’s Law is obeyed (the linear elastic region). Young’s modulus is a measure of the stiffness or rigidity of a material.
