Abstract
Moment of inertia is a fundamental property in Engineering Mechanics used to measure the resistance of an area or body against bending, rotation, and deformation. While regular geometrical sections such as rectangles, circles, and triangles can be analyzed using standard formulas, irregular geometries found in modern engineering components require advanced methods for accurate analysis. This paper presents the use of Computer-Aided Design (CAD) tools for moment of inertia analysis of irregular geometries. Various complex profiles were modeled using CAD software, and their centroidal moments of inertia were calculated automatically. The study compares manual approximation methods with CAD-generated results in terms of accuracy, speed, and design efficiency. Results show that CAD tools provide highly precise and time-saving solutions for engineering applications.
Keywords
Moment of Inertia, CAD Tools, Irregular Geometry, Structural Design, Engineering Mechanics, Section Properties.
Conclusion
Moment of inertia analysis is essential for safe and efficient engineering design. While manual formulas are suitable for standard shapes, irregular geometries require advanced techniques.
This research confirms that CAD tools provide accurate, fast, and reliable moment of inertia analysis for modern engineering components. Therefore, CAD-based section analysis should be integrated into mechanics education and industrial practice.
