A wire of length l0 and cross-sectional area A supports a hanging weight W. Show that if the wire obeys Eq (11.7), it behaves like a spring of force constant AY/l0, where Y is the Young's modulus of the wire. What would the force constant be for a 85.0 cm length of 16-gauge (diameter = 1.291 mm) copper wire? What would W have to be to stretch the wire in part b by 1.75 mm?
