mechanical-strength-review

Perform preliminary, vendor-neutral strength and stiffness screening for small mechanical parts using explicit load cases, free-body diagrams, first-order mechanics, applicability checks, and evidence-aware margins. Use when asking whether a bracket, beam, shaft, pin, boss, snap arm, or similar part may carry a stated load; when estimating stress, strain, deflection, bearing, torsion, thermal expansion, or Euler buckling; or when deciding whether hand calculations, FEM, coupons, or a qualified engineer are required.
