The method of sections is employed to analyze trusses by cutting through specific beams, but it often ignores forces in uncut beams, such as AB and AH. This approach is valid as long as there are no external forces acting on those uncut beams. Internal forces, like AH, are not considered if they do not contribute to the equilibrium of the section being analyzed. The effectiveness of this method relies on strategically choosing which sections to analyze, as some configurations yield clearer results than others. Ultimately, the method of sections simplifies the analysis by focusing on relevant forces while disregarding non-contributory ones.
