In the case of linear deformation, the ratio of tensile stress to tensile strain is called:
Correct answer: D. Young's Modulus
- A. Energy stored in a stretched wire
- B. Young's double slit phenomenon
- C. Bulk Modulus
- D. Young's Modulus
Explanation
The Young's modulus (E) is a property of the material that tells us how easily it can stretch and deform and is defined as the ratio of tensile stress (σ) to tensile strain (ε). Where stress is the amount of force applied per unit area (σ = F/A) and strain is extension per unit length (ε = dl/l).

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.
