Shear modulus is zero for:
Correct answer: D. Liquids and gases
- A. Solids
- B. Liquids
- C. Gases
- D. Liquids and gases
Explanation
The shear modulus measures resistance to a change inshape without a change in volume. Since both liquids andgases lack a definite shape and flow when a shear force isapplied, they cannot resist shear stress, giving them a shearmodulus of zero.

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.
