Here's one way to look at it... For a given material, there is a unique maximum value of strain, ##\epsilon_{max}##, at which fracture... -

That relation only holds if, when the force is removed, the wire returns to it's former length. If you apply enough force the wire will...

Sometimes one has to read the whole problem, start to finish. That is the correct way to initially address the problem. So the answer...

Yes, same strain with longer wire means greater elongation. Take note of two things about your first attempt: you made an assumption...

Hooke's law, by the way, does not work under large stress when the material is about to break.

Not a good assumption. You have not considered what determines when a wire of a given material will break.

Ssongoku replied to the thread Correct statement about size of wire to produce larger extension.I see. I need to consider breaking stress What about the formula: Young Modulus = stress / strain? Does it work under large stress...

Ssongoku posted the thread Correct statement about size of wire to produce larger extension in Introductory Physics Homework Help.The answer is (B) but I don't really understand why. Based on formula of Young Modulus: $$x=\frac{FL}{AE}$$ The second wire made of...

A sample made of a lot of radioactive nuclei started to decay immediately after it was generated.
