SUMMARY
The calculation of the second moment of inertia for a reinforced hollow tube involves summing the individual moments of inertia of the tube and the reinforcement bar, as their centroids coincide. The hollow tube is characterized by a thin-walled circular cross-section with a thickness of 0.1 inches, while the reinforcement bar spans the diameter and also measures 0.1 inches in thickness. For components with offset centroids, an area-weighted summing technique is applied to achieve accurate results. Refer to the I-beam cross-section methodology for detailed calculations.
