- A tightrope walker stands on a wire that is supported by a pole at each end. The tightrope walker creates a tension of 3.42 ✕ 103 N in a wire making an angle 6.2° below the horizontal with each supporting pole. Calculate how much this tension stretches the steel wire (in cm) if it was originally 16 m long and 0.50 cm in diameter. This question keeps getting rejected as incomplete. This is not incomplete. There is no image to accompany it. This is the entire question. PLEASE stop rejecting it. It is getting incredibly frustrating.arrow_forwardA force stretches a wire by 4.0 mm.
