Tensile strain is the change in
Correct answer: A. Length
- A. Length
- B. Area
- C. Volume
- D. All of these
Explanation
Tensile strain is defined as the ratio of the change in length of a material to its original length when subjected to a tensile force. This means it specifically measures the deformation along the length of the object. Option A is correct because tensile strain directly concerns this change in length. Options B and C are incorrect because they refer to changes in area and volume, respectively, which are not directly related to tensile strain. Option D is incorrect because tensile strain is not concerned with all dimensions but only with the length.

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.
