1. The problem statement, all variables and given/known data So in my mechanics of materials lab, we calculated Young's modulus after measuring the strain and applying force to a beam. What I'm trying to figure out is, why are you able to use both a bending force and an axial force when calculating Young's modulus? 2. Relevant equations Young's modulus = stress/strain 3. The attempt at a solution Is it because they both induce a normal force on the beam? Thanks for any help!
