Expression for Young's Modulus in terms of Bulk Modulus.

Young's modulus and Bulk modulus relationship:

Cube showing forces acting on it.

 

This figure shows a cube which is subjected to three mutually perpendicular tensile stresses of equal intensity.

       Let L = Length of cube.

            dL = Change in length of the cube.

             E = Young's modulus of the material of the cube.

      sigma = Tensile Stress acting on the faces

         new = Poisson's ratio.

expression for Young's Modulus in terms of Bulk Modulus is given by
