All right, so you had a question about moment of inertia, and i didn't have a picture of what you're directly referring to in the question, or if you just had a general question about how to find moment of inertia.
00:20
So without a picture, i can't tell you exactly what to do.
00:24
But i did find a nice textbook table of from the surway engineering physics.
00:34
Tracks that talks about how do we find the moment of inertia for the most common types of rotating objects.
00:45
So we've got a hoop about a cylinder.
00:49
We've got a thick cylinder here.
00:53
We've got a solid cylinder that's being rotated around and around on its central point, thin rod, all of these solid sphere, holosphere, hoop of any diameter, including just a particle.
01:11
And a particle would just be nlr squared, how far away that one mass particle is from the center rotation.
01:21
Now, if you do have an irregular object and you know the function of that area or the functional linear relationship of the linear density of the object in terms of mass, we can actually find the moment of inertia for any object...
