(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] Moment of inertia

1. The problem statement, all variables and given/known data

Find the moment of inertia of a thin wire of mass, m, bent into a square without a top, with each side being of length, b, about its axis of symmetry. (looks like field goal uprights)

2. Relevant equations

I = I1 + I2 + I3

3. The attempt at a solution

I know the two uprights I are (m/3)b^2. I found a solution on the net that shows the moment of inertia of the horizontal part being 0 because its center of mass is at the origin. I think that there should still be a 1/12(m/3)b^2 contribution from the horizontal part.
