Brass has greater expansion than iron
WebHowever, since brass expands (or contracts) more than iron when its temperature is raised (or cooled), the bimetallic strip will bend one way or another depending on the … WebA flat bimetallic strip consists of a strip of aluminum riveted to a strip of iron. When heated, the strip will bend.Which metal will be on the outside of the curve? Why? When heated, the aluminum expands more than the iron, because the expansion coefficient of aluminum is larger than that of iron.

WebThese linear thermal expansion coefficients are room temperature values of metals. Linear thermal expansion coefficient is defined as material’s fractional change in length divided by the change in temperature. Coefficient of linear thermal expansion is designated by the symbol α (alpha). The SI unit of thermal expansion coefficient is (°C ... porsche design productsWebMar 2, 2024 · IJessicaI. It expands more because some metals expand more than others due to differences in the forces between the atoms / molecules. In metals such as iron the forces between the atoms are stronger so it is more difficult for the atoms to move around . In brass the forces are a little weaker so the atoms are free to move about more. porsche design readershttp://physics.bu.edu/~redner/211-sp06/class23/class23_expansion.html porsche design roadster briefcaseWebOn heating a bimetallic strip made from brass and iron, both the strips will expand. But, the brass strip will expand more than the iron stip because the linear coefficient of thermal expansion for brass is greater than linear coefficient of thermal expansion for iron.
