There's also some benefit in throwing a moderate safety factor on something if it doesn't actually compromise the intended form or function of the component, just as future insurance. For example, if you design a bit of equipment

They are, somewhat. You can theoretically make a safety factor 1.0 if you're really absolutely certain of the input criteria. Safety factor is really just a (somewhat blunt) method of managing risk. It's just admitting that we don

Oh dear! It looks like someone accidentally divided by 2 for the cylindrical hoop stresses, forgetting that they're not the same equation as for spherical stresses. :) Less facetiously, a thin-walled cylinder's stress is a functio

If you're ever in York in the UK, there's a cool model of Brennan's Gyrostatic monorail car in the National Railway Museum. I had no idea about gyrocars before that and was blown away by the technical prowess of the design fr

I'm not sure how this works for electrified rails (i.e. a third-rail that provides power to the engines), however for a standard rail line (i.e. just 2 tracks, with either an overhead providing electricity, or diesel engines) is used a

No, China if anything is making us take a second look at this creeping authoritarianism and maybe push back on it. Their authoritarian influence on our politics and in other spheres (e.g. universities) is a hot-button politician topic curre

CBD is by no means Sydney-specific, just FYI, it’s a commonly used term in the English-speaking world. Due to the new-world situation of Australia’s cities, the CBD and downtown/city centre basically always overlap (I.e: there’s no ‘ol

Astigmatism can potentially contribute significantly to that, depending on the pattern seen. Mine causes it and it's particularly noticeable at night with street lights.

The rule would manifest itself in some sort of control in the train design/assembly systems, which would forbid a combination of wagons totalling 256 axles. That way, the issue would never reach the shunters who actually assemble the t

The current HSR from Wuhan to HK is USD $96/$154/$298 for 2nd/1st/business class seats respectively. It’s all price regulated, so that’s the cost for every train on that route, every day. You can search here for other co

This doesn’t particularly matter to China. The cost of current HSR tickets isn’t even a free market. It’s all price-regulated so that every ticket for the same journey at the same class costs the same (Not pricing tiers like airlines). They

Yeh they quoted the wrong number.

by NamTaf 7y ago
It’s worth noting that this isn’t necessarily that big of an issue for China. A lot of their HSR is grade-separated and not infrequently up on viaducts. It’s not a particularly big step in my mind to enclosing that.

I’m not sure if it’s just lost in translation, but Wuhan to Guangzhou isn’t even 1000 km so I don’t know where they get the 2200 km they’re quoting. That’s likely a figure for GZ to Beijing. I have used the high speed line between Wuhan and

I can't add much to this, besides the point that in my experience with expansion tunnels [1][2] from my time at uni, they are very short-term test facilities, lasting for fractions of a second. They work by compressing a big vessel of
