Hookes Law for a Wire. A wire of length and cross-sectional area A supports a hanging weight W. (a) Show that if the wire obeys Eq. (11.7), it behaves like a spring of force constant where Y is Youngs modulus for the material of which the wire is made. (b) What would the force constant be for a 75.0- cm length of 16-gauge copper wire? See Table 11.1. (c) What would W have to be to stretch the wire in part (b) by 1.25 mm?
