An aluminum wire is clamped at each end under zero tension at room temperature. The tension in the wire is increased by reducing the temperature, which results in a decrease in the wire’s equilibrium length. What strain (ΔL/L) results in a transverse wave speed of 100 m/s? Take the cross-sectional area of the wire to be 5.00 X 10─6 m2, the density to be 2.70 X 103 kg/m3, and Young’s modulus to be 7.00 X 1010 N/m2.
