Study resources
- Statics Lesson 67: Introduction to Area Moment of Inertia - Prof. Jeff Hanson (Video) — From one of the best-regarded free statics lecture series on YouTube. Clear board work, and the rest of the numbered lessons cover the whole statics syllabus.
- Moment of Inertia and the Parallel Axis Theorem - Seeing Structures (Article) — Explains why we use I-sections rather than solid rectangles, and introduces the parallel axis theorem for built-up shapes. Strong on the 'why', not just the formula.
- Area Moments of Inertia via Integration - Engineering LibreTexts (Article) — Free open textbook section showing the integration method for I, plus polar moment of inertia. Use when the shape is not a standard one from the table.
