Shear force, bending moment, and deflection diagrams for simply-supported and cantilever beams
Defaults: steel (E = 200 GPa), IPE 200-ish section. Sign convention: downward loads, sagging moment positive.
Draws live shear force, bending moment, and deflection diagrams using standard closed-form solutions from mechanics of materials (Euler–Bernoulli beam theory). Supports simply-supported and cantilever beams under a point load or uniformly distributed load — perfect for civil and mechanical engineering coursework, quick design checks, and building intuition about how load position changes the diagrams.
