# Industrial Specification: Crowd Brake

## 1. Technical Definition
A safety component within a crowd management system designed to control or halt the movement of crowds in emergency situations.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.0 m/s² deceleration rate**. Failure boundary: **Exceeds 4.2 m/s² deceleration rate for &gt;2.0 seconds**, Mechanism: **Excessive inertial force exceeding 9.8 kN/m² causes structural yielding in actuator mounting brackets**.

### 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.
