# flywheel-cascade

`station__flywheel__flywheel-cascade` · external (needs EXECUTION_BACKEND_URL configured) · domain `flywheel` · pv-relevance `non-pv`

Momentum L is automatically fed into gyroscopic input.

> **Note:** This tool routes through an external execution backend. If `EXECUTION_BACKEND_URL` is unset on the server, calls return JSON-RPC error `-32603 "Tool execution backend not configured"`. Tools with `backend: native` execute in-process and are always callable.

## Input schema

- `elastic_fatigue_cycles` *integer* (required) — Current fatigue cycle count.
- `elastic_fatigue_limit` *integer* (required)
- `elastic_stress` *number* (required) — Applied stress on system contributors.
- `elastic_yield_point` *number* (required) — Yield point (stress at or above which permanent deformation occurs).
- `friction_automation_coverage` *number* (required) — Automation coverage fraction [0.0, 1.0].
- `friction_human_touchpoints` *number* (required) — Count of human touchpoints (contact friction factor).
- `friction_manual_processes` *number* (required) — Count of manual processes (contact friction factor).
- `friction_velocity` *number* (required) — System velocity for aerodynamic (cubic) drag computation.
- `gyroscopic_critical_momentum` *number* (required) — Minimum L required before gyroscopic stabilization activates.
- `gyroscopic_momentum_l` *number* (required) — Initial angular momentum L (overridden in cascade by momentum result).
- `gyroscopic_perturbation_torque` *number* (required) — External perturbation torque magnitude.
- `momentum_friction_drain` *number* (required)
- `momentum_inertia` *number* (required) — System inertia (mass analog). L = inertia × omega − friction_drain.
- `momentum_omega` *number* (required) — Angular velocity (ω).
- `rim_centrifugal_force` *number* (required) — Centrifugal force pulling the rim outward.
- `rim_tensile_strength` *number* (required) — Tensile strength of the value network rim.
