The ratio of Bulk Modulus is

The ratio of Bulk Modulus is

1. Compressive stress to linear strain
2. Compressive stress to linear strain
3. volume stress to the volume strain
4. Tensile stress to linear strain

EXPLANATION

• Bulk Modulus (K) is a measure of a material’s resistance to uniform compression.

• It is defined as:

K=Volume StressVolume Strain=ΔPΔVVK = \frac{\text{Volume Stress}}{\text{Volume Strain}} = \frac{\Delta P}{\frac{\Delta V}{V}}K=Volume StrainVolume Stress​=VΔV​ΔP​

Where:

• $\Delta P$ is the change in pressure (compressive stress),

• ΔVV\frac{\Delta V}{V}VΔV​ is the fractional change in volume (volume strain).

So among the given options, the correct one is:

Volume stress to the volume strain
