2. A copper segment of length 1.8 m with the cross-sectional area of 0.03 m² is welded to an aluminum segment of length 1.8 m with the cross-sectional area of 0.01 m2. The ends are fixed between two walls that are 3.6 m apart. The temperature of the segments are then changed by -5 C. The moduli of elasticity of copper and aluminum are 80 and 60 GPa, while the coefficients of thermal expansion of copper and aluminum are 1.5 x 10-> and 1.5 x 10-5 C-l, respectively. Determine the stresses in each segments after the temperature change.
