A bimetalic strip consists of a thinstip of brass [Alphabrass=19X106(Co)-1] riveted to a thin strip of steel [Alphasteel=12X106(Co)-1]. What happens when it is heated above room temperature?

it gets longer, stays straight
it gets longer, bends toward the brass strip
nothing changes
it gets longer, bends toward the steel strip.
