3.3 Truss Analysis (trusses)

Purpose: Warren truss axial force analysis under mid-span vertical load.

Method: FEM — pin-jointed bar elements; stiffness $k = EA/L$.

Inputs: span, height, panel count, $A$, $E$, load magnitude.

Outputs: member axial forces (tension/compression), utilization-style summary.

Design codes: Indicative axial utilization.

UI: Modern inputs/results. No unit profile — manual unit state in page.

Gaps: Fixed Warren geometry; no unit profile; no specialized code evaluator.

Maintainer note: Solid structural model with moderate input shape complexity.
