A tight rope walker who weighs 640 Newton walks along a steel cable. When he is halfway across, the cable creates an angle of 0.040 rad below the horizontal.

a) Estimate the strain in the cable? Suppose the cable is horizontal with a tension of 80 Newton before he steps onto it. Neglect the weight of the cable itself.

b) Determine the tension in the cable when the tight rope walker is standing at the midpoint?

c) Calculate the cross-sectional area of the cable?

d) Find has the cable been stretched beyond its elastic limit (2.5x 108 Pa)?
