Single panel truss

This drawing illustrates the forces in a single panel truss for a point load. In mode 0, use the handles to modify the geometry and the load and observe the implications on the magnitude and direction of the reaction forces and the internal forces respectively. In mode 1, use the slider to go through the construction steps: 1) both the supports and the load are constrained; 2) constructing the loadline; 3-5) finding the reaction forces, using a trial funicular polygon; 6) finding the geometry of the truss for the given load through the given support points; 7-8) re-distributing the reaction forces to the supports considering the directions the supports can take.
