Question

Spider silk is one of the most remarkable elastic materials known. Consider a silk strand suspended vertically with a 0.35-g fly stuck on the end. With the fly attached, the silk measures 28.0cm in length. The resident spider, of mass 0.66 g , senses the fly and climbs down the silk to investigate. With both spider and fly at the bottom, the silk measures 37.5 cm. Part A: Find the spring constant of the silk? Part B: Find the equilibrium length of the silk? Express your answer for both parts in two significant figures and include the appropriate units.

Explanation / Answer

The silk thread stretches by an additional (37.5 - 28.0 cm) = 9.5 cm with the addition of .66g Spring constant = 14.4 cm/g Equilibrium length of the thread would be *without* the 0.35g fly 28.0 cm - (14.4 *0.35) = 28.0 - 5.04 = 22.96 cm
