Introduction A truss may be defined as a fabric of beams or posts forming a fixed structure that holds up a bridge, roof, or another structure. Roof trusses are normally triangular-shaped structures that give stability and support to the roof. They also play the role of distributing the roof’s weight away from the outside walls of the building or the structure involved. Trusses can support heavy loads without adding extra weight to the overall mass of the structure. In residential design, trusses are commonly made from wood. For commercial building design, steel trusses are mostly used. Trusses take the triangular shape because of the shape’s natural ability to dispel pressure throughout the whole structure making it highly stable and rigid (Ambrose, 1997). Methods of finding the internal forces Before analyzing methods of finding internal forces, it is important to note that we do have statically indeterminate structures and statically determinate ones. The latter can be analyzed using equations of equilibrium only while the former needs more than these equations to solve it (Somayaji, 1990). A statically determinate truss that has two reactions must satisfy the mathematical equation 2j=m+3 where j represents the number of joints, and m is the number of members in the system. Statically determined trusses can be easily analyzed by the use of the method of joints. Statically indeterminate structures do not satisfy the above-stated equation. Static indeterminacy of planar trusses which are static may be evaluated using the mathematical operation i= (m+r)-2j where m is the number of members, j represents the number of joints, and r shows the unknown reaction components. The number of redundant reactions must be identified and be equal in the degree of indeterminacy. When the selected redundant is directly proportional to the restraints, then the truss resulting is statically determinate stable. Method of joints In this method, we do pick a joint that does not have more than two unknowns and then solve using rules of equilibrium. With the aid of a free body diagram of each joint, the unknown forces at that joint are solved. In this method, you need a Free Body Diagram of each joint and hence solve for the unknown member forces at that particular joint. Once, this joint is completed, move to the next one and solve it. This analysis of joints is done throughout the whole truss and, thus, solves for the force in all the members. A free-body diagram of the whole truss is drawn as the first step, and the external reactions are found if they are required. This is followed by selecting a joint that has only two unknowns, and the roller joint may be the best starting point. The third step is to draw a free body diagram of the joint in question and solve the internal forces with the help of a force polygon. The forces involved here are concurrent and might be either compression or tension forces. The forces found are then transferred to the adjacent joint. Having done these, we go back to our second step, choose a joint with only two unknowns once again, draw the respective free body diagram and solve the internal forces involved until we exhaust all the joints on the truss. It is important to note that if you ha
