Parametric Beam Span Study

Simply supported beam with a midspan load sweeping both load magnitude and span length; reactions stay equal at P/2 regardless of span, while peak moment grows linearly with span — teaches the span-invariance of symmetric reactions.

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.
