when a body is immersed in water then the deforming force applied perpendicularly on all sides of a which change the volume of that body is called bulk stress
there are different types of modulus it depends on what types of stress is acting on the material if its direct stress then then there is modulus of elasticity,if tis shear stress then its modulus of rigidity and when its volumetric stress it is bulk modulus and so on
See Gabriel Lame (1795-1870). Also see Stress-Strain Relationships, Bulk Modulus, and Theory of Elasticity.

The bulk modulus is a measure of a material's resistance to uniform compression. It is defined as a ratio of stress to strain and has units of pressure, typically expressed in pascals (Pa) or psi (pounds per square inch).
Modulus of Compression is the ratio of stress to strain in an uniaxial compression action, while as, bulk modulus is the ratio of volumetric stress (hydrostatic pressure) to volumetric strain in hydrostatic loading. These two modulii are inter-related though and are written with the use of Poisson's ratio. 1/m = (3K-E)/6K 1/m = Poisson ratio K = Bulk Modulus E = Elastic Modulus Satisfied? - tell others, not satisfied? - tell me.
Yes, if the material is very thin in ther axis of compression. If it is not thin, as in compressing a long cyclinder, you do not need to know bulk modulus. If very thin it won't make a lot of difference if it a metal with usual poisson ratio of about 0.25, but will make difference for possion ratio higher, especially approaching 0.5, as in rubber. In the case of the long cyclinder stress = modulus xstrain In the case of the thin material stress = modulus x strain times the quantity (1-u)/ ((1+u)(1-2u)) where u = poisson ratio; the relation to bulk modulus for u is u =1/2 - E/6B where B = bulk modulus and E = elastic modulus
Weightlifting equipment won't stress your breathing and endurance, while cardio equipment won't bulk up your muscles.
Yes, the bulk modulus of elasticity increases with pressure. The bulk modulus measures the resistance of a material to changes in volume under applied pressure. As pressure increases, the material becomes less compressible and therefore the bulk modulus increases.
