    1. ES220 Statics Final Exam Review Notes

    2. Moments of Inertia Chapter 9

    3. Moments of Inertia

    4. Determining Moments of Inertia by Integration

    5. Polar Moment of Inertia

    6. Radius of Gyration

    7. Method of Composite Areas Break complicated areas into several simple shapes Determine I for each shape This is facilitated by use of tables Add the I’s for all the shapes Subtract I for holes Catch: The I’s must all be about the same axis: typically this is the centroid axis of the composite area This requires use of the parallel axis theorem

    8. Examples

    9. Moments of Inertia for Simple Shapes

    10. Parallel Axis Theorem

    11. Example
