Ehh, I don't know what I'm doing. Time to visit the professor. Thanks for trying to help.

So IParallel Axis Theorem = m*[(R - (¼*R))/2]² + m*R for the rod & disc is not at all correct? I am only correct in needing to use the theorem-formula?

Hi & Thanks, Tiny-Tim! Yes, by "Ix-axis parallel", I really meant the equation for Parallel Axis Theorem. You're right: R is 0.31m, not 0.62m. Even so, I take it my Parallel Axis Theorem is not correct for the situation?

Homework Statement Consider a rigid rod-plus-disc system Find the moment of inertia of the pendulum as it freely rotates about the point P. The rod has a length 0.62 m, and the disc has a radius half that. The pivot at P is a fourth of the way from the end of the rod. The rod has a mass of...
