Extracted text: 6. The steel rod is stress-free before the axial loads P-120 kN and P3= 50 kN/are applied to the rod. Assuming that the walls are rigid, calculate the axial stress in segments AB, BC & CD after the loads are applied. Use E 200 GPa. A= 700 mm A=500 mm A=350 mm2 P P2 C 600mm 400 mm- 550 mm
