The discussion centers on a misunderstanding of a shear force and bending moment problem, emphasizing that the real task involves creating separate free body diagrams. The poster is confused about how cutting the cable and removing supports affects forces and moments, mistakenly believing it leads to equilibrium. It is clarified that despite changes in length, the goal is to ensure that all free bodies are in equilibrium by summing forces and moments. The importance of following problem-solving directions is highlighted to achieve the correct solution. The discussion reinforces the need to focus on equilibrium rather than the effects of cutting the mechanism.
