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

Options

  1. Ait will bend towards the right
  2. Bit will bend towards the left
  3. Cit will not bend but shrink
  4. Dit will neither bend or shrink.

Correct answer

B. it will bend towards the left

Step-by-step solution

When the bimetallic strip is kept in a cold bath, the length of X decreases faster and therefore the strip binds towards the left.
