Four steel bars jointly support a mass of 25 x 10³ kg. Initially the temperature is 25°C. Bars A and D have a cross-sectional area of 480 mm². For bars B and C, the cross-sectional area is 360 mm². Determine the elongation of bar A when the temperature becomes 60°C. Also, find the axial stress developed in bar C. Use E = 200 GPa and α= 11.7 x 10 m/ (m°C).
