Problem 2- Consider a square bar with a side length of 20 cm as shown in the figure. The lower side of the bar is kept at 70°C, and the left side of the bar is insulated. Thermal conductivity of the bar is 1.5 W/m°C. The upper and right surfaces of the bar are in contact with the air at 20°C and the heat transfer coefficient on these surfaces are 10W/m2°C. The bar is in steady state condition. Find the temperatures at points 1 and 2 of the bar. (40P)
