Afemale orb spider has a mass of 0.55 g . she is suspended from a tree branch by a 1.2 m length of 0.0020-mm-diameter silk. spider silk has a density of 1300 kg/m3.
if you tap the branch and send a vibration down the thread, how long does it take to reach the spider?

Orb spiders make silk with a typical diameter of 0.15 mm. the young's modulus of spider silk is 0.2×1010n/m2 and its tensile strength is 1000×106n/m2.part a: a typical large orb spider has a mass of 0.50 g. if this spider suspends itself from a single 12-cm-long strand of silk, by how much will the silk stretch? (answer in mm)part b: what is the maximum weight that a single thread of this silk could support? (answer in n)
