# Industrial Specification: Tension Spring Assembly

## 1. Technical Definition
A mechanical assembly consisting of a tension spring and its mounting hardware designed to store and release energy through extension.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **5-150 N tension force, 10-100 mm extension length, -40°C to 120°C temperature**. Failure boundary: **Hooke's law linearity deviation exceeding 5%, permanent set exceeding 2% of free length, spring constant degradation beyond ±15% of nominal value**, Mechanism: **Yield point exceedance causing plastic deformation (σ_y &gt; 0.2% offset yield strength), stress relaxation due to creep at elevated temperatures, fatigue failure from cyclic loading exceeding endurance limit (σ_max &gt; σ_e)**.

### 2.1 Analytical Physics Model
Governed by the **Harmonic Vibration Force Generation**:

> **Primary Equation**: $F_e = m \cdot r \cdot \omega^2 \sin(\omega t)$  
> **Engineering Impact**: Calculates centrifugal force for vibratory sifters/feeders.
