(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

derive the equation for the bulk modulus, K = E/3(1 - 2v), where v is poisson's ratio.

2. Relevant equations

E = stress/e, where e is strain

3. The attempt at a solution

e_v = e_x + e_y + e_z

e_y = e_z = -v*e_x

e_v = (1 - 2v)*e_x

K = stress/e_v

therefore K = stress/[(1 - 2v)*e_x]

i am out by a factor of 1/3. where have i gone wrong?
