**1. Homework Statement**

Hey everyone. I was practicing some problems, and I came across one that seems pretty simple, yet I am having difficulty proving the answer.

__The question asks us to show that a state of pure shear causes no volume change in linear elastic deformation.__I have a very good understanding on shear stresses and strains, however, this problem seems harder then it actually is. If someone could point me in the right direction I would appreciate it greatly!

**2. Homework Equations**

Strain Eq, Stress Eq, Young's Modulus (standard elementary equations)

**3. The Attempt at a Solution**

I have literally spent hours reading my book and working out problems, such as these. I seem to understand all of the formulas, however, I am having trouble proving the statement.
