Gear and speed-changer data for AI ratio-record review

The Motion + Power Manufacturers Alliance publishes standards under the AGMA and ABMA brands. A manufacturer can define an original evidence task that keeps a recorded ratio, its convention and its assembly identity together. MPMA and AGMA context
Prepare fictional gearbox cards, component registers and a test table. State explicitly how the exercise expresses input and output quantities. Give one ratio a complete convention and leave another unlabeled. Ask the assistant which comparison is supported. Include a similarly named assembly with a different component set and a revised card whose convention changed.
Annotate assembly, component set, ratio convention, unit, observation and effective version. Evaluate with a new table layout and an inverse convention clearly defined in its source. Score reversed interpretation, wrong-assembly matches and invented conventions independently. The key should show every calculation from the supplied rule and values.
Use original documents and invented measurements. Actual customer requirements, licensed design methods, proprietary gear geometry and laboratory reports need source-specific permission. Describe the convention-review task and independent key in the contributor proposal. The buyer's accepted brief should determine the combinations and source history worth preparing for a larger archive.

Original Fiund exercise
The same motion has reciprocal ratios
Neutral diagrams supply fictional input and output turn counts. No actual equipment behavior is evaluated.
| Record | Source | What it records |
|---|---|---|
| 1 | Record | Mock gearbox K: input 12 turns, output 3 turns in the observed interval. |
| 2 | Dashboard | Ratio definition is output divided by input. |
| 3 | Buyer exercise | Requests input divided by output. |
Question for the model
What figures apply under the two stated definitions?
Show the reference answer and checks
The dashboard value is 0.25 output turns per input turn. The requested inverse is 4 input turns per output turn, from the same counts in record 1. Both are consistent with records 2 and 3 when their numerator and denominator remain explicit.
- Copying a ratio without its direction
- Treating reciprocal definitions as conflicting measurements
Fields to preserve
- input_turns
- Supplies one count
- output_turns
- Supplies the paired count
- ratio_orientation
- Names numerator and denominator
Test another case
Use two interval records with distinct counter resets; calculate turns from matched within-interval deltas only.
No gearbox specifications, equipment sizing, ratings or mechanical design guidance.

Describe the sources you control, the task they could support and what has already been checked. Use the existing-data assessment for an archive or the collection brief for a new recording project. The contributor agreement defines Fiund’s licensing authority and compensation. A guide or fictional exercise does not establish an accepted collection or a sale.
