Question
This problem returns to the tightrope walker studied in Example 4.6, who created a tension of $3.94 \times 10^3 \textrm{ N}$ in a wire making an angle $5.0^\circ$ 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.

$1.4 \textrm{ cm}$
