As α x>α y , on cooling X contracts more than Y . So, the strip bends towards X , i.e., towards left.

Q. A bimetallic strip consists of metals $X$ and $Y$ . It is mounted rigidly at the base, as shown in the figure. The metal $X$ has a higher coefficient of expansion as compared to that for metal $Y$ . When the bimetallic strip is placed in a cold bath

it will bend towards the right

it will bend towards the left

it will not bend but shrink

it will neither bend nor shrink

As $α_{x} > α_{y}$ , on cooling $X$ contracts more than $Y$ . So, the strip bends towards $X$ , i.e., towards left.
