A steel string guitar is strung so that there is negligible tension in the strings at a temperature of 24.9 oC. The guitar is taken to an outdoor winter concert where the temperature of the strings decreases to -15.1oC. The cross-sectional area of a particular string is 5.5 x10-6 m2. The distance between the points where the string is attached does not change. For steel, Young's modulus is 2.0 x 1011 N/m2; and the coefficient of linear expansion is 1.2x 10-5/Co. Use your knowledge of linear thermal expansion and stress to calculate the tension in the string at the concert.
