The question is- In the metal object below, will the gap between the ends of (B) and (C) become narrower, wider, or remain unchanged if heated? Code (Text): ____________ | | | | (B) | | | (A)| | | | | | (C) | | ------------ This question has been on our class discussion board for two weeks. The class is split 50/50. My answer was- "My thinking is this. Being that the total continuous length of the metal of side (A) is longer than the sum of sides (B+C), and we know that longer objects of the same material (with the same expansion coefficient)expand more, this would mean that the gap between (B) and (C) would get wider because the total expansion of (B + C) would never be equal to or longer than (A)." Am I off base here?
