Question
If there is a circular hole in a metal plate, what
happens to the radius of the hole when the plate is heated?Solution
When a metal plate with a circular hole at its centre is heated, definitely along with the areal expansion of the plate the diameter of the circular hole also increases. Using the differential equations of coefficients of expansions, we find that the hole radius increases at the same linear rate as the metal.
