What to Avoid

Example 1: Direct Stress and Strain (Hearn, similar to Vol.1, Ch.2)

Problem: A steel rod of diameter 20 mm and length 2 m is subjected to a tensile axial load of 50 kN. Calculate the axial stress, strain, and elongation. E = 200 GPa.

Given:
d = 20 mm → A = π(0.02)²/4 = 3.1416×10⁻⁴ m²
P = 50×10³ N, L = 2 m, E = 200×10⁹ Pa. Mechanics of Materials by E

Find: σ, ε, ΔL.

Assumptions:

Solution:

  1. Axial stress:
    σ = P/A = (50×10³) / (3.1416×10⁻⁴) = 1.5915×10⁸ Pa = 159.15 MPa.

  2. Strain: ε = σ/E = 159.15×10⁶ / 200×10⁹ = 7.9575×10⁻⁴.

  3. Elongation: ΔL = ε·L = (7.9575×10⁻⁴)(2) = 1.5915×10⁻³ m = 1.59 mm.

Check (Python snippet – conceptual):

d=0.02; P=50000; E=200e9; L=2
A=3.1416*d**2/4; sigma=P/A; strain=sigma/E; delta_L=strain*L
print(f"delta_L*1000:.2f mm")  # 1.59 mm

Discussion: The elongation is small (<0.1% of length), validating linear elasticity.
