How does the Moment Of Inertia2 D Calculator work?

I = ∫ r² dA where r = perpendicular distance to axis Then: About x-axis: Iₓ = ∫ y² dA; about y-axis: Iᵧ = ∫ x² dA Then: Parallel axis theorem: I = I_centroid + Ad² where d = distance from axis Then: Larger moment = harder to rotate.

Can you give an example of how to use the Moment Of Inertia2 D Calculator?

Example: Input Rod L=1m, center gives a result of I=mL^2/12.
