AI Generated Solution

To find the Young's modulus of the material of the wire, we can follow these steps: ### Step 1: Understand the formula for Young's Modulus Young's modulus (Y) is defined as the ratio of stress to strain: \[ Y = \frac{\text{Stress}}{\text{Strain}} \] ### Step 2: Calculate the Stress Stress is defined as the force (F) applied per unit area (A): ...
