Marks: +1, -0

The relation between bulk modulus (K) and Young's modulus (E) and Poisson's ratio (1/m) is given by:

$K ={ mE }/[3( m -2)]$
$K ={ mE }/[3( m -2)]$
$K ={ mE }/(3 m )$
$K ={ E }/[3( m -2)]$

Solution:

As we known that,
Young’s modulus is defined as the ratio of stress to strain. It describes the linear stress and strain whereas the bulk modulus defines the volumetric stresses and strain.
Youngs Modulus = Stress/ Strain
We have a mathematical between bulk modulus (K) and Young’s modulu s (E) and Poisson’s ratio (1/m) is given by:

K ={ m.E }/[3( m -2)]=E/{3(1-2µ)

Where, µ = 1/m (Poisson’s ratio)
