Homework Help: Hooke's law and elastic deformation

  1. Dec 21, 2016 #1

    3. The attempt at a solution

    I know that spring A shows elastic deformation since it returned to its original shape once the stress removed and spring c shows plastic deformation and has been permanently extended so it won't return to its original shape.

    BUT, I'm struggling to complete the graph for spring C especially since they want it to continue from where the line of spring A ends.....Any ideas?

    What are your ideas on how it looks?

    i would have started by drawing a line above the current line since the original length for C is obviously longer than A but after that i'm not sure, but since it has been deformed plastically and permanently I guess I could draw a line curve showing this?

    The 3 springs are identical, so the line for spring C must start out superimposed on the line for spring A.
