IDS, you were on the right track, the ends of the first two layers do little initially. If you look at a leaf spring the geometry may seem odd, but the bending stiffness is not far off that of a trapezoidal or triangular plate made of the three leaves lying side by side. Crucially the length...
I can help once the rail starts vibrating, but the excitation mechanism is new to me. This paper seems relevant but I can't download it

On the other hand pebble bed reactors have been tried several times

Perhaps we need a geoengineering thread. The main issue is that from any given solution (including reducing CO2 in the atmosphere) there will be winners and losers. An obvious example of this is cloud seeding - if the rain falls on my country it won't fall on your downwind country.

Apparently it is inherently safe and can supply ery high temperature process heat.
Am I right in thinking the currently available LLMs don't actually incorporate what they have learned from user interaction back into their model? For example if ChatGPT told you the sun rose in the West, and you corrected it, and asked the same question in a different session, what would it say?
The tension is shown as -ve, does this mean it is compressive? If the material is linear can I take a punt and guess that Mohr's circle raises its annoying and long forgotten head?
I can't even get it to solve the original problem, never mind a redundant beam.
Here's the problem, I won't bore you with the many iterations of a script that chatgpt created to solve it
Here's a link to the actual solved problem https://engineeringpaper.xyz/9r6KzVsGjtrKvaYWQj5dw2 and I've...
Um, most of the children mining rare earths are in the Congo. Apparently Canadian history books don't mention Africa. Congo was colonised (practically privatised) by King Leopold II of Belgium. This may be news, but Belgium is not the USA, UK or France (a curious list of colonizers in itself).
I get the strong impression it mostly just strings commonly linked statements together and then rewrites them in consistent grammar and spelling, which in itself is quite a feat. It doesn't 'know' anything, or use logic. https://en.wikipedia.org/wiki/Chinese_room is a very badly explained...
To be honest I'd write an Octave script for that. Or if I was lazy, ask ChatGPT to write it and then sort it out myself.
Here's one it did earlier. It is wrong.
So if we ignore the shilly shallying dik's answer would appear to be "Yes, it is acceptable for slave labor to be used to build solar panels, because China has a better human rights record than the USA". Well, I think that statement is all that needs to be said.
