The two equal length and quality of uniform copper and iron bars connected together,And the fulcrum at the junction just balance, when the temperature increased to hundreds of degrees Celsius. The phenomenon is that A is still balanced B, iron fell C, copper decreased
The different coefficient of thermal expansion increased at the same temperature of copper elongation more and more shift as the temperature increased after copper out of the center of gravity, arm becomes much longer, so that the copper end sinking (no map, check their AB)
