Steel Results
Young's Modulus: 2.00 × 10¹¹ Pa
Stress: 1.67 × 10⁸ Pa
Copper Results
Young's Modulus: 1.12 × 10¹¹ Pa
Stress: 1.25 × 10⁸ Pa
Ratio of Young's Modulus (Steel:Copper) = 1.79:1
Physics Formulas:
Stress (σ) = Force (F) / Cross-sectional Area (A)
Strain (ε) = ΔL / L₀
Young's Modulus (Y) = Stress / Strain = (F × L₀) / (A × ΔL)
When ΔL is equal for both wires: Y₁/Y₂ = (L₁ × A₂) / (L₂ × A₁)
