The ratio of volumetric strain to volumetric stress called:
Correct answer: A. compressibility
- A. compressibility
- B. young's modulus
- C. bulk's modulus
- D. shear's modulus
Explanation
Compressibility is the ratio of volumetric strain to volumetric stress. It is the inverse of bulk's modulus. Its SI unit is the pascal. Strain: A force tending to pull or stretch something to an extreme or damaging degree Stress is a quantity that describes the magnitude of the forces that cause deformation (strain).

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.
