Question:

In materials like aluminium and copper, the correct order of magnitude of various elastic moduli is:

Young's modulii < shear modulii < bulk modulii.

Bulk modulii < Young's modulii < shear modulii.

Shear modulii < Young's modulii < bulk modulii.

Bulk modulii < shear modulii < Young's modulii.

As shown in the figure,
The value of various elastic moduli for copper are
Y=128GPa
K=140GPa
η=48GPa
∴for copper η<Y<K
