Method of joints: In this method, free body diagrams of adjacent joints of a member are seen to check the forces acting on different members. Also, “the first joint selected must have two unknown forces and one known force” (Walker 139). The unknown forces are later solved by using ∑x = 0 and ∑y = 0 (Since the whole model is at rest, it is considered that each member in the model will be at rest too). Once the two unknown forces are found, they become known forces to other adjacent joints and are used to find other unknown forces of another member. This technique is used on all the members of the model is found.
b. Method of Sections: This method is usually “used to solve for the force in a member near the middle of truss” (Walker 149). Here, the structure in cut into two pieces; one of the pieces is not used while the other has a force member which is required to find. The free body diagrams of the section which the observers needs are drawn, and after steps similar to methods of joints are
