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
