Answer:
When dealing with structural materials, there are two forces that we generally consider; compression and tension.
Compression is a kind of squeezing force while tension is a kind of pulling force. Different materials handle these things differently. Concrete is excellent under compression … stone doesn’t squeeze very well … but poor under tension (which is why stone bridges usually have an arch of some sort). Iron and steel tend to fare well under both compression and tension, which is why they’re so widely used.
There are three regions into which these forces can exist; elastic, plastic, and failure. In the elastic region, the object is deformed by compression or tension but returns to its original shape once the force is removed. In the plastic region, the object is deformed and doesn’t return to its original shape. In the failure state, the object is no longer whole, no longer able to take a force; it has shattered, snapped off, etc.
Think of a paperclip. Slide a piece of paper between the tongs, remove the paper and it goes back to its original shape. Slide a thick stack of papers between the tongs, remove the paper, and it won’t go back to its original shape. Hammer a wedge through the tongs and it breaks.
So an iron/steel spring compresses and bounces back, despite it being hard. A glass spring would resist compression until it shattered, despite it being hard.
