Question

A copper wire is held at the two ends by rigid supports. At $30^{0} C$, the wire is just taut, with negligible tension. Find the speed of trans- verse waves in this wire at $10^{0} C$. [Given, for copper: Young’s modulus $= 1.3 \times 10^{11} N/m^{2},$ coefficient of linear expansion = $1.7\times 10^ {-5}$ $^{0}C^{-1}$, desity = $9 \times 10^{3} kg/m^{3}.]$].
