AI Generated Solution

To solve the problem of finding the increase in length of a steel wire when stretched, we will use the formula for Young's modulus. Here’s a step-by-step solution: ### Step 1: Convert the given measurements to consistent units - **Length of the wire (L)**: 4 m = 400 cm - **Diameter of the wire (d)**: 5 mm = 0.5 cm - **Radius of the wire (r)**: r = d/2 = 0.5 cm / 2 = 0.25 cm ### Step 2: Convert the force applied to dynes ...
