WebA bimetal bar is usually made of brass and iron. Shows the principle of non-heated (left) and heated (right) bimetal. Bimetallic strips and disks, which convert a temperature change … Web⇒ In theory, any stable metals can be used in a bimetallic strip as all metals expand to some extent when exposed to heat. Choose two dissimilar metals and test their expansion levels by exposing them to heat. Select two metals that expand at very different levels; this disparity is what causes the bimetallic strip to move in the way it does.
WebIn bimetallic strip on increasing temperature the strip bends towards that type for which coefficient of expansion is less and forms concavity towards that side As the coefficient of thermal expansion of the brass is greater than steel. Hence, the length of brass strip will be more than steel strip. Therefore, brass strip will be on convex side. Web4. Fill the small dewar flask with liquid nitrogen and dip the bimetal strip in for a few seconds. 5. Show that the bimetal strip bends to the side with the brass. Notes and …
