(continued from previous message) Showing that the large and small solid
spheres accelerate the same as do the large and small hollow sphere is
also helpful.

Taplers,

I have been looking for a sphere to go with
our rolling disk and ring moment of inertia demo, but Iím
having trouble finding one. I can find sets that include just
the disk and the ring, and I can find sets that include just a
solid sphere and a hollow sphere, but I canít find a set that
includes all 4, or at least one of the spheres with the disk
and ring. All of the objects need have the same mass and
radius, so I canít just put two sets together. I would be
appreciated any ideas.

Thanks,
