Jul 12, 2022 at 16:33 comment added joojaa No trusses are designed out of triangles (because a quad has a degree of freedom) which obviously due to adjacency have 3, 4, 5 or 6 forces on a node. Anyway statics for trusses is usually done by matrix notation as its easy to input and let the computer solve, global minima is relatively easy to search with a computer. Especially since the same notation translates quite easily to a finite element method input this accounts for the beams bending which yout equations dont help with.
Jul 12, 2022 at 16:19 comment added Emmanuel José García I have edited my question to include a generalization for a general quad where I remove the angles restriction. Are cranes designed using quadrilateral of forces? Because all cranes I have seen use a triangle of forces.
