Cart Push Force Start vs Sustained Ratio Checker
Actual same-cart start/sustained push ratios vs caller limit; not allowable push force or general rolling resistance. Caller independently establishes matching units, evidence, method edition and applicability; output is not compliance, diagnosis, work-safety approval, geological identity or validated hazard prediction.
Description
Starting and sustained cart forces describe different phases of movement.
Starting and sustained cart forces describe different phases of movement.1
Their ratio needs a separately chosen review limit and does not establish an absolute acceptable pushing force. Use this tool to calculate cart Push Force Start vs Sustained Ratio Checker from the supplied measurements and assumptions.
When to use Cart Push Force Start vs Sustained Ratio Checker
Use this tool to calculate cart Push Force Start vs Sustained Ratio Checker from the supplied measurements and assumptions. Establish the observation protocol, units, task and reference population or review criterion before entering measurements.
How to use Cart Push Force Start vs Sustained Ratio Checker and understand its results
- Establish the observation protocol, units, task and reference population or review criterion before entering measurements.
- Enter observedStartingPushForcesN, matchedSustainedPushForcesN, callerMaxRatio, using the field meanings and rules below, then run the tool.
- Read startSustainedRatios, callerRatioReviewIndices. Interpret the fields using their units, signs and evidence conventions below.
- If input validation fails, correct the reported field and run again. Before applying the result, check reference scope, model assumptions and any missing evidence or placeholder values.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedStartingPushForcesN | Observed starting push forces n | list of number | Required |
| matchedSustainedPushForcesN | Matched sustained push forces n | list of number | Required |
| callerMaxRatio | Caller max ratio | number | Required |
Enter nonempty aligned nonnegative starting forces, positive sustained forces and one positive maximum ratio. Divide start by sustained for each item and return indices strictly above the supplied limit. Equality is not flagged and no absolute force threshold is installed.
ratio_i=startForce_i/sustainedForce_i; review={i:ratio_i>callerMaxRatio} Use the exact units, boundary rules, ordering and missing-evidence conventions above.
| Output field | Meaning | Value type |
|---|---|---|
| startSustainedRatios | Start Sustained Ratios; follow the units, sign, ordering and evidence convention stated above | list of number |
| callerRatioReviewIndices | Caller Ratio Review Indices; follow the units, sign, ordering and evidence convention stated above | list of number |

}Limitations and assumptions
Their ratio needs a separately chosen review limit and does not establish an absolute acceptable pushing force. Interpretation depends on the units, sampling scope and exact model described above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse evidence arrays fail validation; the specific bounds and alignment requirements are stated above. Extremely large inputs or outputs can also be rejected. An input error is distinct from a successful result reporting false, no matches or missing evidence.
