To solve the problem, we will use the concept of Young's modulus, which relates stress and strain in a material. ### Step-by-Step Solution: 1. **Understand the first wire:** - The first wire has a length \( L \) and a radius \( a \). - A force \( F \) is applied, causing an increase in length \( \Delta L = L \). ...
