| Topic | Moments of inertia |
| Type | Prove MI by integration |
| Difficulty | Challenging +1.2 This is a Further Maths M5 question requiring integration to find moment of inertia, which is inherently more advanced than standard A-level. However, it's a relatively standard setup (equilateral triangle about an edge) with straightforward geometry and a single integral to evaluate, making it a typical FM mechanics question rather than an exceptionally challenging one. |
| Spec | 6.04c Composite bodies: centre of mass |
4. A uniform plane lamina of mass $m$ is in the shape of an equilateral triangle of side $2 a$. Find, using integration, the moment of inertia of the lamina about one of its edges.\\
