A particular human hair has a Young's modulus of 3.31 x 10° N/m2 and a diameter of 145 um. If a 236 g object is suspended by the single strand of hair that is originally 17.5 cm long, by how much AL hair will the hair AL hair = m stretch? If the same object were hung from an aluminum wire of the same dimensions as the hair, by how much ALAI would the ALAI = aluminum stretch? If the strand of hair is modeled as a spring, what is its spring N/m constant khair ? khair = E
