Find the axial forces of the members 2-3, 3-9 of the truss for the given external loads.
From the equilibrium of the forces on the truss we have:
We consider the cross section T so as to calculate the axial forces on members 2-3 and 9-3. We consider the equilibrium of moments to the node 9.
From the equilibrium of forces at Y direction
Structural system identification is a multidiscipl...
