Hooke's law and elastic deformation

AI Thread Summary
Spring A demonstrates elastic deformation, returning to its original shape after stress is removed, while spring C exhibits plastic deformation, remaining permanently extended. The challenge lies in graphing spring C to continue from the endpoint of spring A's line. Suggestions include starting the line for spring C at the same point as spring A and then drawing a curve to represent its permanent deformation. Since all three springs are identical, the initial positions of their graphs must align. The discussion focuses on accurately depicting the differences in deformation for clarity in the graph.

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.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
