In this case, wouldn't the solid expand in all directions? Wouldn't x and y decrease?
If every distance in the solid expands, why would you expect a contraction of the material along the inner edge?MathewsMD said:In this case, wouldn't the solid expand in all directions? Wouldn't x and y decrease?

(No, x and y do not decrease)
Yes, heat can cause a solid to expand in all directions. When a solid is heated, the molecules that make up the solid vibrate faster, taking up more space and causing the solid to expand.
The higher the temperature, the more energy the molecules have and the faster they vibrate. This increase in molecular motion causes the solid to expand in all directions.
Yes, the expansion of a solid in all directions can be controlled by various factors such as the material's composition, temperature, and external forces. For example, some materials have a very low coefficient of thermal expansion, meaning they expand less when heated compared to other materials.
Understanding the expansion of a solid in all directions is crucial in many industries, including construction, manufacturing, and engineering. It helps engineers and designers to account for changes in size and shape of materials due to temperature changes, preventing potential structural failures or design flaws.
In most cases, yes, the expansion of a solid in all directions is reversible. When the solid is cooled, the molecules slow down and come closer together, causing the solid to contract back to its original size. However, some materials, such as rubber, may have permanent expansion due to irreversible changes in their molecular structure.
