The longitudinal strain is only possible in
Correct answer: C. Solids
- A. Gases
- B. Fluids
- C. Solids
- D. Liquids
Explanation
Longitudinal strain is a type of deformation that occurs when a solid is stretched or compressed along its length. Solids can maintain their shape under force and thus can support longitudinal strain. In contrast, gases and liquids (collectively known as fluids) do not have a definite shape and cannot support this kind of strain. Gases expand to fill their container, and liquids take the shape of the container they are in, making them incapable of exhibiting longitudinal strain.

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.
