What is Young's Modulus?

Young's Modulus or Modulus of Elasticity is slope of the initial linear portion of the stress-strain diagram. The modulus of elasticity may also be characterized as the “stiffness” or ability of a material to resist deformation within the linear range.
E (Steel) ≈ 30 x 106 psi 
E (Aluminum) ≈ 10 x 106 psi
