WebIt works because metals expand in different ways when temperature rises. Metal expands when temperature rises - in general, anyway, but not all metals expand the same. Then, if you take two different metals, typically iron and copper, and bind them together in both ends, one metal will try to become longer than the other as the temperature rises. WebNov 23, 2024 · How does a bimetallic strip work at the same temperature? The expansion or contraction of metals is different at the same temperature. The bimetallic strip is constructed by bonding together the two thin strips of different metals. The metals are joined together at one end with the help of the welding. highest rated wooden coat hangersWebDec 13, 2024 · That's the job of the bimetallic strip, which is just a fancy name for two pieces of metal joined together. The reason it works is that the two metals expand at different rates at a given temperature, known as the coefficient of expansion. As one side expands more than the other side, the metal curves one way or the other. how have you experienced god in your own life
