[REPORT ID: ARCH-B1-20260309] STRUCTURAL ANALYSIS: ROMAN PILUM

Technical breakdown of the malleable iron shank and kinetic impact thresholds.

Engineering Parameter Standard Value Material Specification
Total Weight 2.15 kg Weighted Lead Base (optional)
Shank Composition Unhardened Iron Low-carbon (Annealed)
Total Length 2.05 Meters Fraxinus (Ash) Wood Shaft
Bending Strain Threshold 145-160 N Post-Impact Deformation Model

MECHANISM SUMMARY: Upon initial velocity impact (estimated 20m/s), the non-tempered iron shank undergoes immediate plastic deformation. This prevents the weapon from being extracted or re-thrown by opposing forces, effectively neutralizing shield integrity.
