Which of the following describes the region of a force-extension graph where Hooke's law is applicable?.
- A.The linear region up to the elastic limit
- B.The entire graph including plastic deformation
- C.The region after the yield point
- D.The horizontal region of the graph
Model answer
What a good answer should say
- The linear region up to the elastic limit
Explanation
Why this works
Hooke's law applies only in the linear region of a force-extension graph, which is up to the elastic limit. In this region, the force is directly proportional to the extension, allowing for predictable elastic behavior.
