drift toward a wall at a rate faster than the work being done to oppose it

## Emergence
**Emerges from:** [drift](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-drift.aimless), [wall](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-wall.range-end), [parameter](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-parameter.condition), [maintenance](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-maintenance.upkeep), [fast](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-fast.speed), [work](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-work.effort), [toward](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-toward.spatial), [rating](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-rating.evaluation)

**Through:** An aimless drift pushes a parameter toward the end of its allowable range, and the speed of that movement exceeds the rate at which maintenance effort can correct it, causing the condition to degrade.

**Novel properties:**
- unidirectional degradation
- overwhelmed maintenance
- accelerating decline

## Examples
- The Tacoma Narrows Bridge twisted apart in 1940 when wind-driven oscillations overwhelmed structural damping. *(engineering)*
- By 2023, Venezuela’s Orinoco Belt oil output fell below 500,000 bpd despite reserves, as maintenance lapsed. *(economics)*
- In 2017, the LIGO detector’s calibration drifted beyond usable range between scheduled adjustments. *(physics)*
