Initially the bar is horizontal, and the rods are stress-free. The temperature of the rod at A is decreased by 40°C. Neglect the weight of bar ABC. Use α = 11.7 10-6/°C and E = 200 GPa for steel. 1. Calculate the stress in the rod at A (MPa). A. 12.96 C. 10.80 B. 25.92 D. 86.40 2. Calculate the stress in the rod at C (MPa). A. 25.92 C. 86.40 B. 12.96 D. 10.80 3. Calculate the vertical displacement of C, in mm. A. 0.033 C. 0.065 B. 0.812 D. 0.109 Thanks for watching! Comment for questions and suggestions for future lecture in this series.
