A new "Drive Ratio" calculator under /more/calculators for belt, gear, and
chain-sprocket drives, supporting a compound train of 2–6 wheels on a single
shared belt/chain (constant size·rpm across the train).
- Pure, unit-tested math: size·rpm solver, ratio, torque, surface/belt speed,
belt length, sprocket pitch diameter, chain length, gear pitch diameter.
- Mode toggle (Pulley/Gear/Sprocket) with imperial/metric units; torque in
lb·ft or N·m.
- Add/remove wheels (2–6), each with a colorblind-friendly color shared between
its inputs and the schematic SVG diagram (Paul Tol bright palette).
- Dependency-free inline-SVG diagram: colored wheels threaded by one belt/chain,
or meshing gear teeth; auto-fitting viewBox.
- Per-mode details: belt/chain length and center distance (2-wheel only, with an
info popup), per-wheel pitch diameters, and constant train speed.
- Guards against impossible geometry (wheels overlapping) and ideal-torque note.
- Integer teeth enforced in gear/sprocket modes; pulley diameters stay continuous.
Also fix Theme.Header dropping the theme's text color when a caller passes a
`style` prop (now merges {...t.style, ...props.style}).

Getting Started with Create React App
This project was bootstrapped with Create React App.
Available Scripts
In the project directory, you can run:
npm start
Runs the app in the development mode.
Open http://localhost:3000 to view it in your browser.
The page will reload when you make changes.
You may also see any lint errors in the console.
npm test
Launches the test runner in the interactive watch mode.
See the section about running tests for more
information.
npm run build
Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.
Your app is ready to be deployed!
See the section about deployment for more information.
npm run eject
Note: this is a one-way operation. Once you eject, you can't go back!
If you aren't satisfied with the build tool and configuration choices, you can eject at any time. This command will
remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right
into your project so you have full control over them. All of the commands except eject will still work, but they will
point to the copied scripts so you can tweak them. At this point you're on your own.
You don't have to ever use eject. The curated feature set is suitable for small and middle deployments, and you
shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't
customize it when you are ready for it.
