🏛️ Structural Engineering Core Principle: Invisible Force Flow
Just as efficient software architecture eliminates unnecessary intermediate steps and friction points, structural engineering optimizes force transmission by providing direct, unobstructed load paths. When structural nodes are misaligned or support pin friction induces high parasitic moments, stress concentration bottlenecks form. These local stress peaks force engineers to add structural dead weight to prevent failure. Realigning nodes into pure axial tension/compression triangles eliminates localized shear friction, redistributing force uniformly and yielding ultra-lightweight, high-capacity spans.
