Many caterpillars construct cocoons from silk, one of the strongest naturally occurring materials known. Each thread is typically 2.0 μm in diameter, and the silk has a Young's modulus of 4.0 × 10 9 N / m 2 .
a)Assuming that there is no appreciable space between the parallel strands, how many strands N would be needed to make a rope 9.0 m long that would stretch only 1.02 cm when supporting a pair of 91-kg mountain climbers?
N=_____strands
b) Again assuming that there is no appreciable space between the parallel strands, what would be the diameter d of the rope?
d=____cm
