1. The problem statement, all variables and given/known data h = 17.2 cm A = 12.32cm2 E = 410 MPA Fapp = 6130 N 2. Relevant 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!
