A particular human hair has a Young's modulus of 3.71 x 10° N/m² and a diameter of 145 μm. If a 245 g object is suspended by the single strand of hair that is originally 17.0 cm long, by how much AL hair will the hair stretch? If the same object were hung from an aluminum wire of the same dimensions as the hair, by how much ALAI would the aluminum stretch? If the strand of hair is modeled as a spring, what is its spring constant khair? AL hair = ALAI = Khair= m E N/m
