(how do i put an image)I don't know any math, besides algebra.
I know some physics.
http://en.wikipedia.org/wiki/List_of_moments_of_inertia - not there
How do I calculate the angular moments of inertia for a rectangular prism that has it's axis on the side, 1/4 it's length off the side, 3/2 it's length off the side, etc.
What to do if i don't know the mass of the material, but i know it's density.
density / volume = mass ?
if the axis of rotation is in the center, that dimension*mass is/ by 12
if the axis of rotation is on the edge, that dimension*mass is/ by 3
Is it a linear relationship?
