Consider a traffic light suspended from two wires as shown in the figure below. The left wire makes an angle 0 = 29.4° below the horizontal with the top of its pole and carries a tension of 150 N. The 11.7 m tall hollow aluminum pole is equivalent in stiffness to a 4.75 cm diameter solid cylinder. (a) How far (in m) is it bent to the side? m (b) By how much (in m) is it compressed?

Consider a traffic light suspended from two wires as shown in the figure
below. The left wire makes an angle 0 = 29.4° below the horizontal with the
top of its pole and carries a tension of 150 N. The 11.7 m tall hollow
aluminum pole is equivalent in stiffness to a 4.75 cm diameter solid cylinder.

A tightrope walker stands on a wire that is supported by a pole at each end.
The tightrope walker creates a tension of 4.90 x 103 N in a wire making an
angle 4.2° below the horizontal with each supporting pole. Calculate how
much this tension stretches the steel wire (in cm) if it was originally 12 m
long and 0.50 cm in diameter.
