Centroid Calculation Made Simple | First Moment of Area Explained
Centroid calculation using the first moment of area is a core concept in civil engineering, structural engineering, and mechanics of materials.
In this video, you will learn how to calculate the centroid of composite sections step by step, using the first moment of area (Qx and Qy) and a professional table-based method commonly used in real engineering practice.
This tutorial explains:
How to divide composite sections into simple geometric shapes
How to calculate area and centroid coordinates for each part
How to organize data using an engineering centroid table
How to apply centroid formulas to find x̄ and ȳ accurately
How engineers solve centroid problems without memorization
This method is widely used in:
Composite section centroid analysis
Strength of materials
Structural analysis and design
University engineering courses and exams
If you understand how to fill the centroid table correctly, the centroid of any composite section becomes straightforward.
This video is ideal for civil engineering students, structural engineers, and anyone learning centroid calculation from fundamentals to practical applications.
