It seems that they use the obtained value of x-coordinate of the COM, $\frac{R}{6}$, straight away after, without any following up on calculation. Its quite odd, I made a post related to this topic on the maths stack exchange a while back and got exactly the same calculation as the document, using mass moments as an explanation. Many thanks, Aidanaidan12 | |

I believe they split this calculation for a better flowing structure, where the moment of inertia is finalized in context. It looks like mass moment is a name that the TA has given to this partial calculation step representing mass and its area. Furthermore, there is some inconsistent notation with extra and missing $R$s which shows that there is an issue with these steps. | |
| Jul 16, 2019 at 14:35 | comment | added | multipledifferentones | Does this not mean that, when they are calculating the 'mass moments', they should square the two distances that they mention (OC and R/2)? As the formula for Moment of Inertia is the a mass multiplied by the radius of gyration squared? | |
