K-Truss Panel

8 × 4 m K-truss panel with a 60 kN apex load; the K-junction at midspan forces symmetric diagonal tension while the entire bottom chord is zero-force — teaches load-path concentration in K-topology.

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.
