Equal loads are suspended using identical wires of steel and copper. Which wire is elongated more ?

Explanation

To determine which wire, steel or copper, will elongate more when equal loads are suspended from them, we can use the concept of Young's modulus of elasticity. Here’s a step-by-step solution:

### Step 1: Understand Young's Modulus
Young's modulus (E) is defined as the ratio of stress (force per unit area) to strain (relative change in length). Mathematically, it is given by:
\[ E = \frac{F/A}{\Delta L / L} \]
Where:
- \( E \) = Young's modulus
- \( F \) = Force applied (equal load in this case)
