There are five machines located at the points (0, 0), (2, 0), (0, 2), (2, 3) and (4,3) respectively. A repair shop is planned in the facility. The foreman claims that if we use the Resultant Force Diagram method we learned in the class to solve the minisum location problem with rectilinear distances, the optimal location of the new facility we would find can never be at (2,1), regardless of the expected number of repair shop visits of the located machines. State whether this claim is true or false.
