in A-level we often don't worry about which is the dependent variable when doing graphs. Both an stress-strain and a strain-stress graph is okay. The advantage is that in a Stress on the y axis against Strain, the gradient is Young's modulus. Hope this helps!
Super useful for my mocks, thank you for this you're of great help.
Glad to hear! Thanks for the comment!
the stress causes the strain. why is it the dependent variable. hard to get used to this unique convention.why this way

do we need to know about the yield point?
Depends which spec you are doing. If you are doing edexcel, yep
@@zhelyo_physicsWhat about AQA?
yep! It is the point at which you get a big increase extension for small or no change in stress. Hope this helps.
Awesome man
Anytime! Thanks for the comment, much appreciated!

thanks for the comment! Music is now long gone from my videos from around end of 2020 onwards : )
