Worked Example
Centroid and moment of inertia in a real design
The Problem
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.
The Method
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.
