Calculating the angular momentum of rotating objects.
When the angular momentum is computed you add all the individual angular momenta of infinitesimally small masses tilll you get the total, right ?
But doesn't that give a wrong answer - because each tiny piece of the object (rotating disk or whatever) is not just obiting the center, it's also spinning once on its own axis for every revolution of the disk.
So the total angular momentum of real objects will be higher than that for a bunch of particles circling a central axis but maintaining their orientation with no spin.
Do I have this right or am I all wrong ? ;-)
