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 5.75 10-6 m2, the density to be 2.70 103 kg/m3, and young's modulus to be 7.00 1010 n/m2, what strain (δl/l) results in a transverse wave speed of 118 m/s
