A gable truss needs to be designed with a constant force at its bottom chord, see Fig. The constant force on the bottom chord is equal to $100$ kN $.$ Draw the additional diagonals $($zero member forces for this loading case$)$ in each panel by connecting the shortest distance between the opposite joints. Determine the

coordinates of the joints of the truss. The coordinates of the top chord are given as $($ x$,$y $).$ The angle of the roller support in the left side is equal to $10$ degrees. $($Solve the assignment by hand, using a ruler and a triangle$)$
