SUMMARY
The discussion centers on the thermal expansion of materials, specifically addressing the behavior of a square hole in an aluminum plate when heated. The formula δL/L = β*δT is used to describe linear expansion, where β represents the coefficient of linear expansion. As the aluminum plate heats up, all dimensions, including the hole, expand uniformly, resulting in an increase in the area of the hole. This conclusion contradicts the initial assumption that the area would decrease due to differential expansion.
