🧪 *What is the elongation of a bar and how do we calculate it?*
In this video, we explain the concept of elongation in bars subjected to axial loads. You will learn how materials deform under tension, how to apply the standard formula, and how factors like length, area, and material properties affect deformation. Perfect for engineering students, diploma learners, and exam preparation in Strength of Materials (SOM).

⭐ *What You’ll Learn:*

🔹 *Definition of elongation* – What it means in mechanics of materials
🔹 *Axial loading concepts* – Tension, compression & stress
🔹 **Formula for elongation**:
  ΔL = (P × L) / (A × E)
🔹 *Explanation of each term* – Load (P), Length (L), Area (A), Young’s Modulus (E)
🔹 *Step-by-step solved example*
🔹 *Assumptions and limitations*
🔹 *Real-world applications* – Structures, bridges, rods, columns
