I have attached the homework with some of the solution.
I have ciuple of questions about it.
For part b, what else I can say?
I think the copper wite is ductile . Elastic and plastic behaviour have already been mentioned. I need to add another word to describe it. Can say it's hard ? Or should I say it's maleable? The question doesn't make it clear that whether the copper wire is under tention or pressure though. The topic on top of the page says
Tensile testing so I assume it's not under pressure and that's why I think "malaeble " may not be the right word and hard might be better.
In the part c, should I find the gradient of the straight line ?
In part e, should I draw another graph which is less steep in the beginning and generally it's lower than tge first graph and also end at a smaller deformation?
This is because I think if the wite is thinner can tolerate less deformation for the same force and it will have a smaller value for the stiffness and hence a smaller gradient for the straight line .
I appreciate your help.
Thanks
