In this case, wouldn't the solid expand in all directions? Wouldn't x and y decrease?

Homework Help Overview
The discussion revolves around the behavior of solids during expansion, particularly questioning how expansion occurs in different directions and the implications on dimensions such as x and y. Participants are exploring the physical principles behind solid expansion and contraction.
Discussion Character
- Conceptual clarification, Assumption checking
Approaches and Questions Raised
- Participants are questioning why a solid would expand outward without a corresponding contraction inwards. There are attempts to understand the relationship between expansion and the dimensions of the solid, particularly in relation to the inner edge and overall structure.
Discussion Status
The discussion is ongoing, with participants expressing confusion about the nature of expansion in solids. Some guidance has been offered regarding the uniformity of expansion and the avoidance of internal stress, but multiple interpretations of the expansion process are still being explored.
Contextual Notes
There appears to be a visual reference (an image) that is influencing the participants' understanding of the expansion, but specific details about this image or other constraints are not provided.
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:
(No, x and y do not decrease)

Why is it that the solid only increases outward, though? Why does it no expand inwards as well? This would mean x and y (as shown in the picture) are decreasing. I just can't seem to understand why the object would grow in one direction for each component (horizontal and vertical) when looking at this image.

It is growing in all directions - every distance between points increases, as the whole material stretches.
As long as there is no fixed outer border which stops expansion in that direction, a uniform expansion of everything is the best way to avoid internal stress.
It is not a liquid...
