What I'm about to ask isn't a homework question, but it is a personal question relating to a home-project I'm working on.
My question is, what is the moment of inertia of a hollow square tube about an axis perpendicular to its length?
Here's a poor diagram: -----|----- (where | is the axis of rotation)
I've attempted to calcuate it a few times and I'm not sure any of my answers make sense. Then again, I'm pretty rusty on these things and there's probably some key concept I'm missing.
Can anyone offer any help and/or explanation?
Thanks
