=== Assistant: Perfect. ===
Perfect. We’ll add an “Info / Methods” tab (hidden by default; opens via dropdown or “More details” button). It will show the actual math we use plus lots of authoritative links. On the main calculator: results-only. In this tab: full details.

===== - Pitch & Sizing (DP / Module / Circular Pitch) - What DP is; how DP→diameter/radius works https://khkgears.net/new/gear_knowledge/gear-nomenclature/diametral-pitch.html - Module basics; circular pitch in metric; conversions DP↔Module https://khkgears.net/new/gear_knowledge/abcs_of_gears-b/basic_gear_terminology_calculation.html https://khkgears.net/new/gear-module.html - Spur rack notes; circular pitch → rack tooth count https://shop.sdp-si.com/products/gears-differentials-pinions-racks/spur-gear-technical-information.html =====
* Torque ↔ Linear Force (drum/pinion) - Definition of torque; F=τ/rF = \tau / rF=τ/r relationship https://phys.libretexts.org/Bookshelves/University_Physics/University_Physics_I_-_Classical_Mechanics_(Gea-Banacloche)/09%3A_Rotational_Dynamics/9.04%3A_Torque https://en.wikipedia.org/wiki/Torque
* Static Breakaway vs Running Losses - Bearing starting torque + running friction/power loss (why breakaway threshold exists) https://www.skf.com/group/products/rolling-bearings/principles-of-rolling-bearing-selection/bearing-selection-process/operating-temperature-and-speed/bearing-friction-power-loss-and-starting-torque?Information=true - SKF frictional moment model (reference background) https://cdn.skfmediahub.skf.com/api/public/0901d1968065e9e7/pdf_preview_medium/0901d1968065e9e7_pdf_preview_medium.pdf
* Mesh Efficiency (rack–pinion tooth contact) - General gear meshing loss concept (we expose η_mesh, default 0.99, min 0.85) https://sdp-si.com/resources/elements-of-metric-gear-technology/index.php
* Angle / Projection Effects (our “angle loss %”) - Resolving a force along a direction (cosine component) https://openstax.org/books/physics/pages/5-4-inclined-planes
* What we deliberately do NOT use here - Capstan equation (we are spools with fixed length, not capstans) https://en.wikipedia.org/wiki/Capstan_equation
* Assumptions (clearly stated) - Aluminum pinion/drums (context only) - Kevlar cord; mass neglected; capacity sufficient - Identical drums; r_d = r_p; fixed 4″ pinion spacing - One pair of arms only; angles/lengths mirrored; Calculate button—no live updates

Want me to draft the exact labels/text for that tab (what the user will read) using these links?
