Review. An aluminum wire is held between two clamps under zero tension at room temperature. Reducing the temperature, which results in a decrease in the wire's equilibrium length, increases the tension in the wire. Taking the cross-sectional area of the wire to be 5. 00 \times 10^{-6} \mathrm{~m}^{2} the density to be 2. 70 \times 10^{3} \mathrm{~kg} / \mathrm{m}^{3} , and Young's modulus to be 7. 00 \times 10^{10} \mathrm{~N} / \mathrm{m}^{2} , what strain (\Delta L / L) results in a transverse wave speed of 100 \mathrm{~m} / \mathrm{s} ?
