Solids have distinct mechanical properties.
- **Elasticity and Plasticity**:
- Elastic bodies return to original shape after deformation.
- Plastic bodies undergo permanent deformation.
- **Stress and Strain**:
- Stress = Force/Area.
- Strain = Change in length/Original length.
- **Hooke’s Law**:
- Stress is directly proportional to strain (within elastic limit).
**Possible Exam Questions:**
1. Define elasticity and plasticity.
2. Explain stress and strain with their types.
3. State and explain Hooke’s Law.
4. What is Young’s modulus? How is it measured?
5. Discuss practical applications of elasticity in engineering.
