# Industrial Specification: Reject Arm

## 1. Technical Definition
Mechanical arm that physically removes defective beverage containers from the production line after leak detection.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 m/s linear velocity, 0.1-0.3 m reach, 5-15 N actuation force**. Failure boundary: **Actuation force exceeds 20 N, positional accuracy exceeds ±2 mm, cycle time exceeds 0.8 seconds**, Mechanism: **Servomotor torque saturation at 2.5 N·m due to inertial load acceleration of 3.5 m/s², leading to positional overshoot and mechanical resonance at 8-12 Hz**.

### 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.
