SqExp = expected result for moment of inertia using equation 106. SqAct = actual equation for moment of inertia.

For some reason, equation 106 did not yield the same results as the actual equations for moment of inertia for reasons of which I am uncertain. We found that the moment of inertia changes based on the shape of the object in motion. For instance, the disc has a much higher moment of inertia than the square....
