A bimetallic strip consists of two metals: A on top and B at bottom. At temperature 00C this bimetallic strip was rigidly attached to the vertical wall with one end, so strip is horizontal. We know that coefficient of thermal expansion of metal A is less than coefficient of thermal expansion of metal B. Temperature starts to raise. What happens to the bimetallic strip? a it expands in horizontal direction b nothing happens c it bends up d it bends...
Thin strips of brass and copper of equal length are used to construct a bimetallic strip. When the strip is heated, due to the difference in the coefficient of linear expansion of the two metals, the brass strip will have a greater increase in length than the copper strip, causing them to bend into an arc with the brass on the outside of the curve. When the temperature of s by 25.8 C, the angle subtended by the two ends...
A bimetallic strip" consists of two thin strips of different metals fastened together like two slices of bread in a sandwich. If the bimetallic stip is held horizontally where the bottom strip is brass, with a coefficient of expansion 1. 5 times greater than the coefficient of expansion of steel strip. The strip is straight at room temperature: a) but. will bend upward when the strip is heated b) but will bend downward when the strip is heated c) will...
