Didn't think of it like that, it certainly is easier to imagine the disk expanding and just taking out the middle. I think I was just too focused on width and not length. Thanks again!

So we don't include width because it expands just as much as length, and because the formula gives a percent change the expansion will also change by the same percent? That would definitely explain why the hole gets larger. Thank you for your time, I appreciate it!

I see... If it expands more on the length, the hole would definitely expand. The formula only accounts for length, why not width too or area? The formula appears to not seem to care about width. I do apologize for not including the formula, I felt as if it couldn't help in this problem due to...

The ring example confuses me more. If I had a ring and turned in into a line, then added heat, the line would be bigger as your picture shows. But if I were to turn it into a ring again, I would still expect the hole be smaller than the original hole. For instance, say the line initially had a...

Thank you for the welcoming! The corners would expand squeezing the middle(top,left,right, bottom) tiles to where the only direction the inner blocks can go is towards the hole and away from the hole. So because of this I would still say the hole gets smaller from the initial area that it had...

Homework Statement This is more of a question that doesn't require formulas as much as common sense. The question goes,"If you have a ring that is heated up, would the hole in the middle get smaller or larger." Homework Equations N/A The Attempt at a Solution I know that when objects are...
