Hook's law defines
Correct answer: C. Modulus of elasticity
- A. Stress
- B. Strain
- C. Modulus of elasticity
- D. Elastic limit
Explanation
Hooke's law states that the strain in a solid is proportional to the applied stress within the elastic limit of that solid. This relationship is characterised by the modulus of elasticity, which quantifies how much a material will deform under a certain amount of stress. Therefore, Hooke's law defines the modulus of elasticity. Stress and strain are related concepts within Hooke's law, but they are not what the law defines. The elastic limit is the boundary beyond which Hooke's law no longer applies.

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.
