Luckily we have engineers who design cars with thermal expansion in mind so things don’t fall apart, however, the 2 towers were poorly designed, and the expansion of the horizontal girders caused the collapse. As for how far things expand, it depends on the length of them, a pot will not expand more than a mm or 2, where as a railroad track will expand a great deal, even in the sun.
Please see the picture in this article, and read the article, its a good explanation:

fyi, its spelled Occam’s razor, the simple lest solution is usually the correct one.
