Problem 5 The grid in figure 2, describes the temperature distribution of a system. At equilibrium, the temperature at each node is the average of the temperature in the neighboring nodes. a) Write the system of equation that allows you to find the temperatures Ti, T2, 73 and T. b) Solve the system and find the values of the temperature at the nodes.30 40 80 K A C 2, E D 20 4 0 FIG 1 20 O .
