Haunched Beam — Decreasing Distributed Load
4 m fixed cantilever with a 1 m unloaded segment at the wall and a trapezoidal load (12 → 4 kN/m) on the outer 3 m; teaches decomposition of a trapezoidal load into uniform + triangular blocks to find reactions.

Solution
| Support | Rx (N) | Ry (N) | Mz (N·m) |
|---|---|---|---|
| A (Fixed Wall) | 0 | 32 | 53.333 |
All reaction values are computed by the StatIQ structural engine, not generated text. Signs follow the solver's convention: a positive Ry acts upward, a negative Ry downward; a positive M is counter-clockwise.
