__1. Homework Statement__

h = 17.2 cm

A = 12.32cm

^{2}

E = 410 MPA

F

_{app}= 6130 N

__2. Homework Equations__

**Stress**

σ = F/A where F is force applied and A is cross sectional area of side where force is applied

**Strain**

ε = ΔL/L where L is the length of the bar and ΔL is the change of length of bar

**Young's Modulus**E = stress/strain = FL/AΔL

__3. My attempt at solution__

We are solving first solving for ΔL which I got as 0.864cm and then we subtract that from 17.2cm which I got as 16.34cm

I'm not sure if my thought process is correct or how to approach this question. What is Young's modulus ? Am I approaching the problem correctly? Am I looking for the right variable? Did I get the correct answer ? Just need reassurance. Thanks in advance guys!
