- Size of hole in a constrained metal when heated.
I have seen many discussions on the topic of whether a hole in a metal will get larger or get smaller when the metal is heated. And the conclusion is the hole will get larger. My question is if the metal is constrained so the outside dimension of the metal cannot expand, what happens to the hole in the center.
Example: a one quarter inch thick disk, two inches in diameter with a one inch hole in the center. The metal is heated. The two inch disk is not allowed to expand or get thicker. What happens to the dimensions of the one inch hole?
Thanks,
Tom
