# Industrial Specification: ROPS/FOPS Cab

## 1. Technical Definition
Safety-certified operator enclosure for underground mining trucks that provides protection against rollovers and falling objects.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-150 kN static load, 0-50 kJ impact energy**. Failure boundary: **Structural deformation exceeding 150 mm at any point, or penetration exceeding 12.5 mm at 10 kJ impact energy**, Mechanism: **Plastic yielding of ASTM A572 Grade 50 steel beyond yield strength of 345 MPa, or localized buckling under Euler critical load of 785 kN for 100 mm square tubular members**.

### 2.1 Analytical Physics Model
Governed by the **Frame Structural Deflection Analysis**:

> **Primary Equation**: $\delta = \frac{5 q L^4}{384 E I}$  
> **Engineering Impact**: Ensures structural stability for multi-stage machines.
