A brass disc fits snugly in a hole in a steel plate. Should you heat or cool this system to losen the disc from the hole ? given that `alpha _b gt alpha _Fe`.

first heated then cooled

first cooled then heated

is heated

is cooled

Text Solution

Verified by Experts

The correct Answer is:

Since the cofficient of linear empansion of brass is greater than of steel. On cooling the brass contracts more, so it get loosened.
