An aluminum alloy [E = 72 GPa; ν = 0.33; α = 23.0 × 10–6/°C] plate is subjected to a tensile load P. The plate has a depth of d = 255 mm, a cross-sectional area of A = 6500 mm2, and a length of L = 4.6 m. The initial longitudinal normal strain in the plate is zero. After load P is applied and the temperature of the plate has been increased by ΔT = 68°C, the longitudinal normal strain in the plate is found to be 2570 με. Determine: (a) the magnitude of load P. (b) the change in plate depth Δd.
