The ratio between applied stress to the volumetric strain is called

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.
