The area of stress verses strain graph is
Correct answer: C. Energy density
- A. Energy
- B. Work
- C. Energy density
- D. Elasticity
Explanation
The area under a stress-strain graph represents the energy density. This is because the graph shows how stress varies with strain, and the area under the curve indicates the energy stored in the material per unit volume as it is deformed. 'Energy density' is the correct term, while 'energy' and 'work' are related concepts but not precise. 'Elasticity' is a property of materials, not the area under the graph.

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
