AI Generated Solution

To find the maximum length of a steel wire that can hang without breaking, we will use the relationship between breaking stress, density, and the dimensions of the wire. ### Step-by-Step Solution: 1. **Understand the given data:** - Breaking stress (σ) = \(7.9 \times 10^{12} \, \text{dyne/cm}^2\) - Density of steel (ρ) = \(7.9 \, \text{g/cm}^3\) - Acceleration due to gravity (g) = \(980 \, \text{cm/s}^2\) (approximate value) ...
