Why does the iron-carbon phase diagram go only to 6.7% carbon? Aluminum (E = 70 GPa, a = 23.0 E-6 1/°C) piece BE is held in place by rigid member DEF as shown here. Piece BE is 50 cm long and has a diameter of 5 cm. Steel (E = 200 GPa, a = 11.7 E-6 1/°C) rods AD and CF are 60-cm-long and have a 0.5-cm-diameter. Initially the bolts are tightened until all clearances are zero and no load is applied to any member. The temperature of this assembly now increases by 100 °C. What is now the stress in the support rods? A E Multiple Choice B 8.73 GPa 9.02 GPa 14.3 GPa C Why does the iron-carbon phase diagram go only to 6.7% carbon?
