important difference is that you are not dealing with a large mass of the
material. Also your ring gear is not cast iron so you are able to heat it
with a torch..

So, if the ring was lengthened into a cylinder, then the atoms would contract
instead of expand when heated? The laws of physics do not change with the
shape of the material.
Also, assuming the ring gear is made of steel, the gear is in fact mainly
comprised of the same raw material-iron ore.
