It is not possible to tell where E is on the graphs provided, because there is no way of knowing whether the material will return to its initial length when the stress is removed. You would have to do other tests to find out where E is. 2. In my definition the limit of proportionality is at the end of the linear region, which is quite far to the right in graph D. However, it all depends on what definitions you use. The linear region for D does not pass through the origin, so the behaviour is not strictly proportional. | |
Jul 4, 2017 at 8:03 | comment | added | Pancake_Senpai | At which point would you say the elastic limit is on D, roughly? Is it even possible to tell? Also, I understand from your answer that the limit of proportionality is marked as the end of any proportionality, not just the part that follows Hooke's Law. Is that what you meant? | |
