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 4.0×109 n/m2. assuming that there is no appreciable space between the parallel strands, how many strands would be needed to make a rope 8.8 m long that would stretch only 1.02 cm when supporting a pair of 85-kg mountain climbers? = strands again assuming that there is no appreciable space between the parallel strands, what would be the diameter of the rope?
