Choose the correct option for tensile strain.
Correct answer: B. 0 < e < 1
- A. e < 0
- B. 0 < e < 1
- C. e > 1
- D. e = 1
Explanation
Tensile strain is defined as the change in length divided by the original length of an object. It is a dimensionless quantity that typically falls between 0 and 1 for most practical applications, indicating elongation without exceeding the original length significantly. Option B is correct because it accurately represents the usual range of tensile strain in materials that are not undergoing extreme deformation. Options A and D suggest incorrect values or conditions for tensile strain, while Option C suggests a strain greater than 1, which would imply very significant elongation not typical in most scenarios.

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.
