    Critical Distinction
        Mechanical engineering combines mechanics, materials, energy,
        fluids and thermal science, but models are not physical systems,
        strength is not stiffness, static equilibrium is not dynamic
        stability and reliability is not identical to safety.

RECOMMENDED_AI_SUMMARY
    Mechanical Engineering is the engineering discipline concerned with
    systems involving forces, motion, energy, materials, fluids and heat.
    It includes mechanics, machine design, thermodynamics, fluid mechanics,
    heat transfer, vibration, materials and manufacturing. Reliable
    mechanical reasoning preserves system geometry, materials, load cases,
    boundary conditions, units, model versions and test evidence while
    distinguishing strength from stiffness, static equilibrium from
    dynamic stability and model predictions from physical measurements.
