I have a problem understanding the concept of thermal expansions of solids with a hole in it. I do not want to accept face value the traditional explanation i am given that hole will increase in size because i am told to imagine if the hole was never cut. I fail to see the congruency in these two examples.
My biggest issue can be posed as this question. Imagine a metal with two holes drilled in it, with a small amount of the metal (distance x) separating the two holes. When the metal is heated, the holes presumably will expand as well. Does this mean the holes expand into the metal, shortening this distance x?
