Overview

When forces are applied to solids, they may change shape or size. Some materials return to their original form after the force is removed, while others do not. This behavior depends on a fundamental property called elasticity. In this chapter, we explore how solids respond to external forces, the in

Key Concepts

Elasticity is the ability of

Elasticity is the ability of a body to regain its original shape and size after removal of deforming force. Plasticity refers to permanent deformation

Stress is the internal restoring force

Stress is the internal restoring force per unit area, measured in Nm⁻². Strain is the ratio of change in dimension to original dimension and has no un

Within the elastic limit

Within the elastic limit, stress is directly proportional to strain. The constant of proportionality is the modulus of elasticity. This linear relatio

Young’s modulus relates to longitudinal stress

Young’s modulus relates to longitudinal stress and strain, bulk modulus to volume changes under pressure, and rigidity modulus to shearing stress and

Poisson’s ratio is the ratio

Poisson’s ratio is the ratio of lateral strain to longitudinal strain. Elastic potential energy is stored in a stretched wire due to work done against

Learning Objectives

  • Distinguish between elastic and plastic bodies
  • Define stress, strain, and their types
  • Understand and interpret stress-strain curves
  • Explain Hooke’s Law and its limitations
