This effect is used in a range of mechanical and electrical devices. Mechanical clock mechanisms are sensitive to temperature changes as each part has tiny tolerance and it leads to errors in time keeping. A bimetallic strip is used to compensate this phenomenon in the mechanism of some timepieces. The most common method is to use a bimetallic construction for the circular ri… WebDec 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.
