WebFeb 13, 2024 · We calculate the strain is the rod according to the formula:. We calculate the stress, using the stress formula: σ = F/A = 30×10³ / (1×10⁻⁴) = 300×10⁶ = 300 MPa. Finally, we divide the stress by strain to find the Young's modulus of steel: E = σ/ε = 300×10⁶ / 0.0015 = 200×10⁹ = 200 GPa.
