Internal forces in a three-hinged frame - superposition

The internal forces in a three-hinged frame for the combined load case of a line load and a horizontal point load are determined using the principle of superposition. The diagrams of the internal forces for each load case are constructed separately. Their superposition provides the diagrams for the combined load case.
Move the hinge and observe the implications for the N-, V- and M-Diagrams. Find the optimal location for the hinge for each load case.
