Bogus answer to squeeking fan belt puzzler

Yeah but if the metal all around the hole is expanding, wouldn’t it expand into the hole and make it smaller?

If that happened a disc of metal would get thicker in the middle when heated. It doesn’t.

We had this discussion here about 10 years ago, I think.

Yep, 10 years ago:

Torpedo tube analogy

On the show I heard today you were explaining to “The Chief of the Boat” that his master cylinder heating up was like a heated torpedo tube expanding, and therefore the torpedo would fit looser in the tube. Actually the opposite is true. The heated tube would expand in ALL directions; making the inside diameter of the tube smaller, not larger. The torpedo would fit tighter in the tube, not looser.
