For a constant hydraulic stress on an object the fractional change in the object's volume (

V/V) and its bulk modulus are related as _______

a)(

V/V)

B

b)(

V/V)

1/B

c)(

V/V)

B²

d)(

V/V)

B^-2

B = NORMAL STRESS(HYDRAULIC STRESS) / VOLUMETRIC STRAIN

Volumetric strain = /_\ V/ V

B =

P/(-

V/V)

Hence (

V/V)

1/B

By defintion of Bulk modulus

B= F

_______

(

V/V)

so it is inversley proportional to B.
