Longitudinal strain is possible in:
Correct answer: C. Solids
- A. Gases
- B. Liquids
- C. Solids
- D. All of these
Explanation
Longitudinal strain (change in length per unit length)requires a material to have a definite shape to resist tensileor compressive forces. Only solids possess this property,while liquids and gases will flow.

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.
