Propped Cantilever — Indeterminate Classifier

Fixed-wall cantilever with an added roller prop under a UDL; introduces statically indeterminate classification (DSI = 1) — the engine correctly refuses to solve and explains why compatibility is required.

Category: beam · Difficulty: Intermediate

Solution

engine returns least-squares (does not decline) — client determinacy indicator is the honest signal

All reaction values are computed by the StatIQ structural engine, not generated text. Signs follow the solver's convention: a positive R_y acts upward, a negative R_y downward; a positive M is counter-clockwise.
