problem returns to the tightrope walker studied in Example 4.6, who 3? created a tension of 3.94×10? N in a wire making an angle 5.0º 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. Example 4.6: Calculate the tension in the wire supporting the 70.0-kg tightrope walker shown in Figure 4.17. Figure 4.17 The weight of a tightrope walker causes a wire to sag by 5.0 degrees. The system of interest here is the point in the wire at which the tightrope walker is standing.

Step-by-step solution Step 1 of 4 The radius of the rope is the half of the diameter Step 2 of 4 The cross sectional area of the rope
