An important concern in the study of heat transfer is to determine the steady-state temperature distribution of a plate when temperature around the boundary is known. Assume the plate shown in the figure represents a cross section of a metal beam, with negligible heat flow in the direction perpendicular to the plate. Let A, B, C, and D denote the temperatures at the four interior nodes of the mesh in the figure. The temperature at a node is approximately equal...
