# Industrial Specification: Variable Speed Auger

## 1. Technical Definition
A mechanical component that transports meat through the grinder at adjustable speeds.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **50-500 RPM**. Failure boundary: **Exceeding 650 RPM causes helical shaft deflection exceeding 0.5 mm/m, leading to contact with housing**, Mechanism: **Centrifugal force-induced shaft bending (F = mω²r) at critical rotational speed, combined with torsional resonance at 600-650 RPM**.

### 2.1 Analytical Physics Model
Governed by the **L10 Bearing Life & Fatigue Model**:

> **Primary Equation**: $L_{10} = (\frac{C}{P})^p$  
> **Engineering Impact**: Predicts mechanical lifecycle before component fatigue.
