The Correct Option is
Solution and Explanation
Step 1: Understanding the Concept:
Young's modulus (elastic modulus) and shear modulus are measures of a material's resistance to deformation under stress.
Step 2: Detailed Explanation:
Solids have a definite shape and can resist both tensile (stretching) and shear (twisting) stresses. Liquids and gases (fluids) cannot resist shear stress; they flow. Young's modulus is defined for solids under tensile or compressive stress. Shear modulus is defined for solids under shear stress. These moduli are not defined for liquids or gases because they do not exhibit a fixed shape and cannot sustain a shear force without continuously deforming (flowing).
Step 3: Final Answer:
Young's modulus and shear modulus can be defined only in solids.
Young's modulus (elastic modulus) and shear modulus are measures of a material's resistance to deformation under stress.
Step 2: Detailed Explanation:
Solids have a definite shape and can resist both tensile (stretching) and shear (twisting) stresses. Liquids and gases (fluids) cannot resist shear stress; they flow. Young's modulus is defined for solids under tensile or compressive stress. Shear modulus is defined for solids under shear stress. These moduli are not defined for liquids or gases because they do not exhibit a fixed shape and cannot sustain a shear force without continuously deforming (flowing).
Step 3: Final Answer:
Young's modulus and shear modulus can be defined only in solids.
