An aluminum rod with a gauge length of 1.18 m undergoes thermal expansion from 20 oC to 92 oC. The thermal expansion coefficient and elastic modulus of aluminum are 22.2 × 10−6 K −1 and 68.9 GPa respectively

Consider a 1.2 meter high and 2 meter wide glass window whose thickness is 6 mm and thermal conductivity is 0.78 w/m °c. the room temperature is maintained at 24 °c, while the outdoor temperature is -5 °c. the convective heat transfer coefficients on the inner and outer surfaces of the window are 10 w/m2 °c and 25 w/m2 °c respectively. (a) draw the thermal resistance network, etermine the steady rate of heat transfer t e glass window (c) determine the temperature of the inner surface of the window
