Question:

A metal wire, with density p and Young's 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 + ΔT, the speed decreases to V2 < v1 Determine the coefficient of linear expansion of the wire
