# Industrial Specification: Telescopic Crane

## 1. Technical Definition
A mobile crane with a telescoping boom that extends and retracts hydraulically for lifting and moving heavy loads.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **17.2-34.5 MPa (2500-5000 psi) hydraulic pressure, 0.5-3.0 m/s boom extension/retraction velocity, -40°C to +50°C ambient temperature**. Failure boundary: **Hydraulic pressure exceeding 41.4 MPa (6000 psi) causes cylinder seal extrusion failure, boom deflection exceeding 1/500 of span length (L/500) causes permanent plastic deformation, hydraulic fluid temperature exceeding 93°C (200°F) causes viscosity breakdown**, Mechanism: **Hydraulic cylinder seal failure due to extrusion at pressures exceeding material yield strength (Hooke's Law violation), boom structural failure due to Euler buckling under compressive loads exceeding critical load P_cr = π²EI/L², hydraulic fluid thermal degradation following Arrhenius equation with activation energy of 80-100 kJ/mol**.

### 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.
