Understanding centroids and area moments of inertia is crucial for passing the FE exam. These topics form the foundation for structural and mechanical analysis, showing up frequently in statics, strength of materials, and mechanics of materials problems. On this page, you’ll get a comprehensive FE exam centroids and area moment of inertia review designed to help you master these important concepts. From identifying the centroid of complex shapes to calculating moments of inertia for composite areas, our practice problems, explanations, and examples are tailored to simplify what can often feel like tricky topics.
Our approach includes clear video tutorials, a smart interactive quiz, and real-world examples to make sense of the formulas and theory behind these problems. Whether you’re brushing up before the test or learning these concepts for the first time, this guide provides a focused, exam-relevant review to boost your confidence on test day.
Video Tutorial: Learn Centroids and Area Moments of Inertia Visually
To support your FE exam centroids and area moment of inertia review, we’ve created a step-by-step video tutorial walking through typical FE exam problems. In the tutorial, you’ll learn how to find the centroid of composite shapes using the method of divided areas, and how to apply the parallel axis theorem to determine the area moment of inertia for combined regions.
The benefit of this video is that you can pause, rewind, and rewatch parts that are unclear — making it a flexible study tool. Many students find that visual learning makes abstract concepts like centroids and moments of inertia much easier to understand, especially when dealing with irregular or composite areas.

Real-World Example: Centroid and Moment of Inertia in Action
Imagine you’re working on the design of a steel I-beam for a pedestrian bridge. You need to determine the centroid of the I-shaped cross-section to assess its balance and calculate the moment of inertia to evaluate how well it will resist bending when loaded.
Using the method of divided areas, you would break the I-beam’s cross-section into three rectangles, find the centroid of each, and then use those values to compute the overall centroid of the section. Next, applying the parallel axis theorem allows you to compute the moment of inertia of each rectangle about the centroidal axis and sum them for the entire section. These values are essential for ensuring your bridge safely handles applied loads — exactly the type of practical application you’ll be asked about on the FE exam.
