C8 — Hinge-pin Factor of Safety

Paper claim: The Ti-6Al-4V hinge pin maintains a F.S. > 1.5 under worst-case 50g axial deployment shock.

Recomputed result: Bending Stress: 466.5 MPa Shear Stress: 12.0 MPa Von Mises Stress: 466.9 MPa Ti-6Al-4V Yield Strength: 880 MPa Factor of Safety (F.S.): 1.88

The computed F.S. of 1.88 exceeds the model threshold. This analytical comparison is not a measured load test or a qualification result.
