5.3 Exercise 23

This problem returns to the tightrope walker studied in the reference, who created a tension of $3 . \text{94} \times \text{10}^{3} N$ in a wire making an angle $\text{5}.\text{0}º$ below the horizontal with each supporting pole. Calculate how much this tension stretches the steel wire if it was originally 15 m long and 0.50 cm in diameter.
