Beam with Partial UDL on Left Half

8 m simply supported beam with a 30 N/m UDL covering only the left 4 m; the asymmetric load shifts 75% of the reaction to the pin, and the peak moment at x = 3 m exceeds the value at the load boundary.

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.
