SUMMARY
The assertion that in a bimetallic strip of brass and copper, the brass is on the inside of the curve when heated is false. Brass has a higher coefficient of linear expansion compared to copper, which means it expands more when subjected to heat. Consequently, when heated, the brass will expand faster, causing the strip to curl with the brass on the outside of the curve. This behavior is governed by the principle of thermal expansion, specifically described by the equation deltaL = alpha * Lo * deltaT.
