To solve the problem step by step, we will follow the reasoning outlined in the video transcript. ### Step 1: Understand the Concept of Stress Stress is defined as the force applied per unit area. In this case, the material breaks under a stress of \( 20 \times 10^5 \, \text{N/m}^2 \). ### Step 2: Identify the Force Acting on the Wire When a wire is hanging, the force acting on it due to its own weight can be expressed as: \[ ...
