The method of joints in structural steel members along with calculations
The method of joints is one of the simplest methods for determining the force acting on the individual members of a truss because it only involves two force equilibrium equations.
Since only two equations are involved, only two unknowns can be solved for at a time. Therefore, you need to solve the joints in a certain order. That is, you need to work from the sides towards the center of the truss.
Since you need to work in a certain order, the Method of Sections (which will be covered later) can be more useful if you just want to know the forces acting on a particular member close to the center of the truss.
