## Homework Statement

A large book has forces of magnitude 14 N applied in opposite directions to two opposite faces of area 42 cm

^{2}. The thickness of the book (L) is 2.0 cm. The deformation angle (g) is 8.4°.

1) what is change in X?

2) What is young's modulus for the book?

## Homework Equations

I tried getting change in x doing 2cos(8.4) but I'm horrible at trig. What should I have done?

Once I do that, I can just plug it all into F/A = S*deltaX/L

Right?

What should I be doing to get the change in X?
