Stress-Strain Graphs - A Level Physics

This video introduces and explains stress-strain graphs for A Level Physics.

Building on a force-extension graph for a particular object, we can produce a stress-strain graph (or stress-strain curve or stress-strain diagram) for a particular material (not the object). A stress-strain graph is directly proportional until the material reaches its elastic limit.

Thanks for watching,

These videos are incredible! They are such a brilliant revision resource to quickly an effectively go over all the key ideas and concepts. Thank you :)

Arrrgh it hurts seeing springs that have undergone plastic deformation. It's so unsatisfying!!! xD

[gurjeetkahlon]

Your videos are awesome, thank you! Will you be covering A2 physics soon?

[Hannah-lruc]

Why aren't the axes the other way around? I've always struggled to get my head around these graphs and I think that's why. Aren't you changing the force, and hence the stress, so shouldn't that be on the x-axis? I know you are not wrong I just wonder why it is done this way around.

Do we need to know the yield point for a level aqa

[atypical]

:o You just ruined a perfectly good spring! >:(

UTS and fracture point are not identical
