my book says the yield point is the minimum stress that causes plastic deformation. Is this correct and if so how is it different to the elastic limit?
It has always been a bit ambiguous whether it is in the specification or not. I have seen in in past exam questions however which is why I included it. You should know what the material properties e.g ductilility look like on a graph which is definitely in the specification.
"Description of plastic behaviour, fracture and brittle behaviour linked to force-extension graphs." This is the part of the specification that I would link it to so I think it is yes.

Thank you so much for this impeccable video. I am a DON at materials now!!!!!!!! #swaggy
for me the speech is way ahead of the video? so it is hard to follow

the champ john cena ... He said that?
do we need to know how to draw the raphs for differet materials? i cant find it in the spec

Burrows Physics I mean for the new spec

Fantastic. Just the video I was looking for.
you didn't define Ductile
...nice.
