Parametric Truss Height
Symmetric 5-member truss with apex height h; demonstrates that chord forces scale as 1/h while the vertical web always carries the full 60 kN regardless of h — a direct demonstration of how truss depth controls efficiency.

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.
