So, why aren't they circular like portholes?
- em-bee 7y agowell, if you look at the first photo in the article, they actually were completely circular. i suppose eventually people decided to compromise and found out how much roundness is enough.
- taneq 7y agoYou can probably get 80% of the stress reduction from 20% circularity.
- Gibbon1 7y agoDefinitely that. Also for a cylinder under pressure the hoop stress is twice the longitudinal stress. Which says to me that vertically oriented rectangular windows are optimal. Probably even more so since the windows are aligned.
