In figure which strip brass or steel have higher coefficient of linear expansion.

brass strip

steel strip

both strips has same coefficient of linear expansion

cannot be decided from given data

Text Solution

Verified by Experts

The correct Answer is:

As the coeffiecient of thermal expansion of the brass is greater than steel. Hence, the length of brass strip will be more than steel strip. Therefore, brass strip will be on convex side.
