You mentioned at the end you were gonna make an example on finding mass moment of inertia for nonuniform rods. Is there anyway you could share this example? please
I was really confused with this question. Especially when I was about to calculate the moment of inertia in the unknown shape,which you called it a bob. Cheers 🍻
it all depends on which formula you use, the 1/3 consider the axis to be passing through the top end and the 1/12 considers the axis to passing through the center of gravity / centroid of the object/ shape see the below links images.slideplayer.com/24/7344486/slides/slide_5.jpg www.desktopclass.com/wp-content/uploads/2012/09/Moments-of-inertia-of-various-bodies.gif
Awesome Vid dude thanks a lot!

for the last one why did you not square the (m+l)
Little late, but shouldn't you have squared the last term (r+L)?
where is the center of gravity video? thanks
In last. ( r+l)^2
At the end, shouldn't (r +L) be (r + L)²?
yes you are right
yup thats right! good catch!
Ah finally
Where did the 1/12 come from and why did it reduce to 1/3?

Pace is really slow on this one.
I am working on better videos in the future, stay tuned!
