Overview
Elongation is the increase in length of a material when subjected to a tensile force. Within the elastic limit, this follows Hooke's Law and depends on the material's stiffness.

Pro Tips
Formula: ΔL = (F * L) / (A * E).
Ensure units are consistent (e.g., meters for length, m² for area, Newtons for force, and Pascals for modulus).
Stress (σ) = F / A, and Strain (ε) = ΔL / L. Young's Modulus E = σ / ε.

Fun Facts
"Steel is very stiff (high E), so it elongates very little under heavy loads."
"Rubbers have low Young's Modulus and can elongate hundreds of percent before breaking."
"The 'Ductility' of a material is often expressed as the percentage elongation at the point of fracture."
