SUMMARY
The moment of inertia of a cylinder can be calculated about its center of mass using the formula ∑miri². The discussion highlights the calculation of Izz as straightforward, while Iyy and Ixx present challenges that may require the application of double integrals. The parallel axis theorem is also mentioned as a useful relationship for simplifying calculations, particularly when transitioning from a disk's moment of inertia around an axis through its center in its own plane.
