# Industrial Specification: Rotary Drilling Rig

## 1. Technical Definition
A heavy-duty machine used for drilling deep holes in the ground for various applications including water wells, oil and gas exploration, and geotechnical investigations.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-689 bar (0-10,000 psi) hydraulic pressure, 0-300 rpm rotary speed, 0-500 kN pull-down force**. Failure boundary: **689 bar hydraulic pressure (10,000 psi) causes seal extrusion, 350 rpm rotary speed induces drill string resonance, 550 kN pull-down force exceeds derrick structural yield strength**, Mechanism: **Hydraulic seal failure occurs at 689 bar due to elastomer extrusion through clearance gaps exceeding 0.1 mm; drill string resonance at 350 rpm matches natural frequency of 5.83 Hz causing fatigue failure; structural yielding occurs at 550 kN pull-down force exceeding A36 steel yield strength of 250 MPa**.

### 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.
