## Main Question or Discussion Point

I have a question on finding the inertia of a rod with a pivot point somewhere along it's length.

So the inertia of a rod is I

Does L

m*L

If it's the second one then may I ask why it's that?

Picture

So the inertia of a rod is I

_{Stick cm}= 1/12 *m*L^{2}Does L

^{2}= (2L/3)^{2}= 4L^{2}/9 -> 1/12 *m*[4L^{2}/9] or is it something likem*L

^{2}/12 + m* (2L/3)^{2}?If it's the second one then may I ask why it's that?
