The ratio between applied stress to the volumetric strain is called
Correct answer: A. Bulk modulus.
- A. Bulk modulus.
- B. Shear modulus.
- C. Young's modulus.
- D. Modulus of plasticity.
Explanation
The correct concept for the ratio between applied stress and volumetric strain is the bulk modulus. However, the given correct option 'Young's modulus' is incorrect for the provided question. Young's modulus is specifically the ratio of stress to strain in the linear elasticity regime of a uniaxial deformation. The bulk modulus is indeed the correct term for volumetric stress-strain relationships. Therefore, the question seems to be incorrectly keyed.The other options are incorrect as follows:Shear modulus: Involves shear stress and shear strain, not volumetric strain.Modulus of plasticity: Is not a recognized term in standard material science terminology.Young's modulus: Refers to tensile stress and tensile strain, not volumetric changes.

About Deformation and Elasticity
Deformation and elasticity describe how solids change shape or volume under an applied force and return to their original form when the force is removed. Work includes stress, strain, Hooke’s law, elastic limit, Young’s modulus and elastic potential energy, while elastic deformation must be distinguished from permanent plastic deformation.
