This is more of a concept that I am confused on.
IF there are 2 metals, one on top of the other, and they are attached to each other and attached to a wall, and the only thing different between the two metals is the thermal expansion. When heated will the metal curve down or upwards?
The Attempt at a Solution
Assuming the metal with the higher thermal expansion is on top, I thought it would curve towards the smaller thermal expansion, which would be downwards.
