An aluminum alloy [E = 70 GPa; v = 0.33; a = 23.0x10-6/°C] bar is subjected to a tensile load P. The bar has a depth of d = 270 mm, a cross-sectional area of A = 13520 mm², and a length of L = 4.5 m. The initial longitudinal normal strain in the bar is zero. After load Pis applied and the temperature of the bar has been increased by AT = 46°C, the longitudinal normal strain is found to be 1830 μ⁹. Calculate the change in bar depth d after the load P has been applied and the temperature has been increased.
