A spring is stretched by applying a load to its free end. The strain produced in the spring is
Correct answer: C. Longitudinal and shear
- A. Volumetric
- B. Shear
- C. Longitudinal and shear
- D. Longitudinal
Explanation
When a spring is stretched by a load, it experiences two types of strain: longitudinal and shear. Longitudinal strain is due to the change in length of the spring along the direction of the applied force. Shear strain occurs because the coils of the spring also deform, changing their shape. Option C is correct because both types of strain are present. Option D is only partially correct as it only considers longitudinal strain. Option A is incorrect because volumetric strain involves a change in volume, which is not the primary deformation here. Option B is incorrect because shear strain alone does not account for the entire deformation of the spring.

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.
