Q. An orb weaver spider with a mass of 0.27 g hangs vertically by one of its threads. The thread has a Young's modulus of 4.7 x 109 N/m2 and a radius of 8.7x10-6 m.

(a) What is the fractional enhancement in the thread's length caused by the spider? Similar as that of the spider's thread?

(b) Suppose a 76 kg person hangs vertically from a nylon rope. What radius must the rope have if its fractional enhancement in length is to be the similar as that of the spider's thread?
