Problem 12: Consider the effect of wires hung on poles in which the left wire made an angle 29° below the horizontal with the top of its pole and carried a tension of 114 N. The 13 m tall hollow aluminum pole is equivalent in strength to a 4.1 cm diameter solid cylinder.

The figure shows an approximate plot of stress versus strain for a spider-web thread, out to the point of breaking at a strain of 2.20. The vertical axis scale is set by a = 0.160 GN/m²,b = 0.500 GN/m?, and c = 0.720 GN/m². Assume that the thread has an initial length of 0.700 cm, an initial cross-sectional area of 7.00 × 10-12 m², and (during stretching) a constant volume. The strain on the thread is the ratio of the change in the thread's length to that initial length, and the stress on the thread is the ratio of the collision force to that initial cross-sectional area. Assume also that when the single thread snares a flying insect, the insect's kinetic energy is transferred to the stretching of the thread. (a) How much kinetic energy would put the thread on the verge of breaking? What is the kinetic energy of (b) a fruit fly of mass 5.50 mg and speed 2.20 m/s and (c) a bumble bee of mass 0.440 g and speed 0.840 m/s? Would (d) the fruit fly and (e) the bumble bee break the thread?…
