Chapter 17, Problem 17.8(choose chapter or problem)
A metal wire, with density r and Youngs modulus Y, is stretched between rigid supports. At temperature T, the speed of a transverse wave is found to be v1. When the temperature is increased to T + T, the speed decreases to v2 6 v1. Determine the coefficient of linear expansion of the wire.
