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. I asked this question THREE times and it was rejected the first two for being incomplete. It is not incomplete. There is no accompanying image. The third time, it was answered . . . incorrectly. I am very annoyed that I keep wasting my limited question attempts on ONE question that I am trying to understand how to do.

A steel cable 3.00 cm2 in cross-sectional area has amass of 2.40 kg per meter of length. if 500 m of the cable ishung over a vertical cliff, how much does the cable stretch underits own weight? Take Ysteel=2.00 X 1011N/m2.

A force stretches a (first) wire by 2mm. This wire is made of an unknown material and has a 1.2cm diameter and 3.5cm length. A second wire of the same material has the same cross-section and three times the length. How far will it be stretched by the sameforce?

A uniform brass plate with area of 18 x 18 m?, has mass of 3 kg which is hold by three cables in the horizontal position as shown. Please calculate the tension in each cable. B A 6 m. 9 m. 12 m. 9 m. ANSWERS TA (N) TB (N) Tc (N)

A man whose weight is 0.80 KN is standing upright. By Papproximately how much is his femur shortened compared to when he is tying down? Assume that the compressive force on each femur is about half his weight. The average cross-section area of the femur is 8.0 cm² and the length of femur when lying down is 43.0cm

A cable used to lift heavy materials like steel I-beams must be strong enough to resist breaking even under a load of 1.7  106 N. For safety, the cable must support twice that load. (a) What cross-sectional area should the cable have if it's to be made of steel?   (b) By how much will a 7.0-m length of this cable stretch when subject to the 1.7  106-N load?

A ladder leans against a frictionless vertical wall. If the ladder is uniform, has a mass of 5kg, and 2.5m long, then what is the friction on the bottom of the ladder when it sits at an angle of 75◦ with a 85kg person standing 1m from the top?

A steel wire 2.3 mm in diameter stretches by 0.030% when a mass is suspended from it. How large is the mass?

How large a force is necessary to stretch a 2.0-mm-diameter steel wire (Y = 2.0 x 1011 N/m2) by 1.0%?
