Mechanics And Fluid Dynamics Codexery — Data & Quality

We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.

Last full accuracy audit: 2026-08-29 · 10 entries checked · 2 flagged · 3 issues confirmed · 2 corrected · 1 still open

Recent findings (audit lane, verbatim)

Euler–Lagrange equation — The statement that the Euler–Lagrange equations are equivalent to Newton's laws of motion is a factual oversimplification; they are equivalent only under certain conditions (e.g., holonomic systems with conservative forces), not universally.

Impact (mechanics) — The claim 'many stiff materials are highly impact-resistant' is a factual error because stiffness does not guarantee impact resistance; many high-modulus materials like ceramics and glass are brittle and have low impact resistance.

Impact (mechanics) — The claim about perfectly inelastic collisions misattributes the primary energy conversion mechanism: kinetic energy is primarily dissipated through plastic deformation and internal energy changes, not directly into heat and sound as the main process.
