Shear strain is equal to
Correct answer: D. Angular deformation
- A. Δx/L
- B. ΔL/L
- C. ΔL/x
- D. Angular deformation
Explanation
Shear strain is a measure of how much a material deforms under shear stress, typically defined by the angle change (angular deformation) in radians. In other words, it is the tangent of the angle of deformation due to applied shear forces. The incorrect options relate to the definitions of linear or normal strain (Δx/L and ΔL/L) or do not apply to standard strain measurements at all (ΔL/x).

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.
