Question
A sheet of metal has a hole of diameter 10cm. If the sheet is heated by 100°c what will be the diameter of the hole?
Solution
To answer this question, we need to know the coefficient of linear expansion of the metal. The coefficient of linear expansion (α) is a material-specific constant that measures how much a material expands per degree change in temperature.
The formula to calculate the change in diameter due to therm
