A solid square bar of cross-sectional dimensions 50mm x 50mm is attached rigidly to the wall at point A and has a gap of 1mm from the rigid wall at point B at 25 "^{\\circ}C" . Knowing the bar is made of aluminum ( E= 70 GPa , "{\\alpha}"= "23\\times10^{-6} /^{\\circ}C" ):

What stress exists in the bar at a temperature of 100 "^{\\circ}C"?

rigid bar attached to wall A, with a small gap between 
              right edge of bar and wall B 0.8m
