## Description

Cross Section Calc is a free structural engineering app for quickly checking and exploring cross-section properties.<br>By entering dimensions, you can instantly calculate section area, second moment of area (moment of inertia), section modulus, and neutral axis position.<br><br>The app also includes a powerful reverse calculation feature that determines the minimum required dimensions from a target section modulus (Z) or moment of inertia (I).<br>This makes it easy to search for efficient cross-sections that satisfy required performance values.<br><br>Designed for both engineering education and practical design studies, the app provides a simple and intuitive workflow.<br>It is lightweight, fast, and fully usable offline.<br><br>■ Key Features<br>• Tap to select cross-section shapes<br>• Supports 27 section types including rectangular, circular, I-shape, H-shape, T-shape, and more<br>• Create custom composite sections by combining rectangles<br>• Save section data<br>• Instant calculation results while entering dimensions<br>  - Section area<br>  - Second moment of area (moment of inertia)<br>  - Section modulus<br>  - Neutral axis position<br>• Reverse calculation from required section modulus (Z)<br>• Reverse calculation from required moment of inertia (I)<br>• Helps find minimum cross-section dimensions that satisfy required performance<br>• Input units: mm / in<br>• Output units: mm / cm / m / in / ft<br>• Offline support<br>• Lightweight and fast performance<br>• Free app with ads<br><br>■ How to Use<br>1. Select a cross-section shape<br>2. Enter dimensions or required performance values<br>3. View results instantly<br><br>■ Disclaimer<br>Calculation results provided by this app are for reference purposes only.<br>While efforts have been made to ensure accuracy, completeness, and suitability are not guaranteed.<br>Consult a qualified professional for critical design decisions.<br>The developer assumes no responsibility for any damages resulting from use of this app.
