Since the two metals are different, they have different specific
heats meaning they expand to different lengths with the strip with
larger linear coefficient of expansion ()
iron = 12 * 10-6 ,
brass = 19 * 10-6 meaning that brass expands more making
a circular strip as shown below:
If flat strips of iron and brass were bonded together and this bimetallic strip were heated,...
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...
