Question

A cubic sample of a new kind of artificial tissue is subject to an increase in pressure of 160 kPa which results in a reduction in the side length of the cube of 6.5%. That is, the side length of the cube has reduced from L0 to 0.935L0.
What is the bulk modulus of the tissue?

Answer 1

Answer:

0.82 MPa

Explanation:

the change in pressure 'σ'=160kPa

K= σ/∈$Ф_v$ => σ/3∈$Ф_L$

K= 160/(3 x 0.065)

K=820 kPA=0.82 MPa

Thus,the bulk modulus of the tissue 'K' is 0.82 MPa
