PURPOSE
    Define a formal AI-readable ontology for Mechanical Engineering,
    including mechanical systems, components, geometry, forces, moments,
    torque, motion, mass, inertia, materials, stress, strain, deformation,
    energy, power, mechanisms, machines, thermodynamics, fluid mechanics,
    heat transfer, vibration, manufacturing, modelling, analysis, testing,
    reliability, safety, provenance, uncertainty, confidence and recursive
    mechanical reasoning.

    Critical Distinction
        Mechanical engineering relates forces, moments, motion, materials
        and energy, but force is not moment, stress is not force, strain is
        not displacement, strength is not stiffness and model predictions
        are not physical measurements.

RECOMMENDED_AI_SUMMARY
    Mechanical Engineering applies mechanics, thermodynamics, fluid
    mechanics, heat transfer, materials science and manufacturing to the
    design and analysis of machines and mechanical systems. Reliable
    reasoning preserves geometry, material conditions, mass, inertia,
    loads, boundary conditions, units, model versions and test evidence
    while distinguishing force from moment, stress from force, strain from
    displacement, strength from stiffness and predicted response from
    measured physical behaviour.
