Two dimensional modulus of elasticity is given by
Correct answer: B. Y/σ²
- A. Y/σ
- B. Y/σ²
- C. Y/σ¹
- D. All of the above options are correct
Explanation
The correct expression for the two-dimensional modulus of elasticity is Y/σ², where Y is the Young's modulus and σ represents stress. This expression accounts for the squared relationship of stress in two-dimensional scenarios. Option A Y/σ and Option C Y/σ¹ imply incorrect relationships, while Option D All options are correct is incorrect, as it suggests multiple correct answers, which is not the case.

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.
