Multiple moments of inertia
http://hyperphysics.phy-astr.gsu.edu/hbase/perpx.html Web4 mar. 2024 · A body where all three principal moments of inertia are distinct, I 1 ≠ I 2 ≠ I 3, is called an asymmetric top. Some molecules, and nuclei have asymmetric, triaxially-deformed, shapes. Orthogonality of principal axes The body-fixed principal axes comprise an orthogonal set, for which the vectors L and ω are simply related.

Web28 nov. 2012 · The mass moment of inertia of a rectangular plate through the center of the plate is m* (h^2+w^2)/12. With mass m=ρhw, this becomes ρhw* (h^2+w^2)/12. Setting ρ=1, h=w yields I=w^4/6. Mass moments of inertia in 2D land often grow by the fourth power, so the numbers get big fast. – David Hammen.
