Engineering Library — Index

Engineering-substance reference across all major disciplines: mechanical, electrical/electronic, materials, control, structural, civil, chemical, biomedical, aerospace, manufacturing, software (embedded/real-time), industrial, thermal, fluids. Sister project to Robotics/ (which integrates these) and Languages/ (which catalogues their description-languages).

  • Status: scaffolding (2026-05-14). Tier 1 deep-note set pending user confirmation.
  • Library structure: mirrors Languages/ — Tier 1 deep per-topic notes + Tier 2 deferred + Tier 3 family indexes.
  • Schema: see _schema
  • Roadmap: see _roadmap

Tier 3 — Family indexes

See _index for the encyclopedic discovery layer (steel grades, beam profiles, motor types, op-amp variants, fastener taxonomy, bearing styles, gear families, etc.).

  • Latest addition (2026-05-31): power-semiconductor-devices — power semiconductor device family catalog (diode / BJT / MOSFET / IGBT / SiC / GaN / thyristor).

Adjacent libraries

  • Robotics — robotics-specific engineering (kinematics, manipulator design, mobile bases, perception). Sits on top of Engineering.
  • Languages — description / specification languages for engineering (IFC, STEP, gbXML, EnergyPlus IDF, IEC 61850 SCL, etc.) are catalogued there.

How to study this library

  • Learning paths — _learn_next — “if you’ve read X, learn Y next” recommendation graph plus six named multi-step tracks (Mechanical-design engineer, Aerospace GNC engineer, Power-electronics + EV engineer, Civil-structural engineer, Biomedical-device engineer, Manufacturing / process engineer).
  • Cross-cutting comparisons — two _compare_* notes that span the library: _compare_control-strategies, _compare_materials-selection-criteria.

How to use

For a design task across disciplines:

  1. Identify the discipline and the note type (concept / material / component / process / standard).
  2. Open the appropriate Tier 1 deep note.
  3. If you need a quick survey of alternatives (“what stainless steels are there?”, “what op-amp packages?”), jump to the matching Tier 3 family index.
  4. Cross-reference into Robotics for application context if relevant.
