## Young's Modulus (Elastic Modulus)
Young's modulus E is the slope of the linear portion of the stress-strain curve. It measures a material's stiffness, or resistance to elastic deformation.
### Formula
**E = sigma / epsilon**
where sigma is the axial stress and epsilon is the axial strain (both in the elastic region). E is an intrinsic material property independent of geometry.

Esempio Risolto
A steel specimen shows 200 MPa stress at 0.001 strain (0.1%) in the elastic region.
- E = 200 MPa / 0.001
- E = 200,000 MPa = 200 GPa
- This is consistent with structural steel (E ≈ 200 GPa)
