Out-of-plane bending stress on an I-beam

AI Thread Summary
The discussion focuses on understanding the origin of the out-of-plane bending stress equation for a curved I-beam, specifically sigmaR = tFlange * sigmaNormal/(radius of curvature). Participants emphasize the need to clarify what "out of plane" refers to in this context. One user indicates they may have resolved the issue and plans to share their findings. There is a request for confirmation on whether the answer has been found, highlighting some unreadable text in the shared materials. The conversation reflects a collaborative effort to clarify complex engineering concepts related to I-beam stresses.

TL;DR Summary
out of plane bending stress
I know the out of plane bending stress equation for a curved I beam but I am trying to figure out where it came from. sigmaR = tFlange * sigmaNormal/(radius of curvature)

You need to define what you are thinking about as "out of plane." This is out of what plane?
 
I think I may have figured it out. Let me finish what I have on paper

Thread 'A practical way to vaporize fuel for high MPG?'

Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...

Thread 'Turbocharging carbureted petrol 2 stroke engines'

Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...

TL;DR Summary: Heard in the news about using sonar to locate the sub Hello : After the sinking of the ship near the Greek shores , carrying of alot of people , there was another accident that include 5 tourists and a submarine visiting the titanic , which went missing Some technical notes captured my attention, that there us few sonar devices are hearing sounds repeated every 30 seconds , but they are not able to locate the source Is it possible that the sound waves are reflecting from...
