Skyscraper's Lethal Secret - Massive Engineering Mistakes - S01 EP8 - Engineering Documentary

[@jasonpeisley6031]

I don't understand the demonstration/experiment in the first case with the skyscraper bolts. I fail to see the correlation between bolts the size of a human arm and a bullet even if that size. They're 2 completely different things. The first experiment was a 50 calibre bullet which is meant to replicate a bolt falling from the 3rd floor. But I fail to see the similarities because the bolt would do MUCH more damage to a pedestrian walking underneath the building. Can someone please help me make sense of this? 😅😂 Also she said the first shot wouldn't have been fatal, but how does she know that. Just because it did minimal external damage doesn't mean it wouldn't have had the same effects to a humans head. In my opinion, both shots, even the first one would have been fatal regardless. Sure you'd have a higher chance of survival in the first shot, but wouldn't be a huge difference. But what do I know? It's just what's going through my mind. And I'm no expert on either subject.

@jason, you might not be an expert, but clearly neither was the person involved in this ill conceived and irrelevant experiment. Perhaps they should have consulted their neuroscientist or the dude that fetches the coffee?

We've all seen a bullet go through a melon. Show a god damned bolt the aize of an arm falling on a melon.

[@paultaylor6821]

You are right. This was bellicose.

[@AbbStar1989]

I don't get it either. Why not at least use ballistic gel? Why use a bullet and not send a steel bar? Surely these two things were possible when this film was made. It doesn't feel very scientific to me.

[@brassitaschannel-tu5yw]

As a civil engineer, I wonder when I get to be a subject matter expert in a neuroscience documentary. Good grief.

The streets of Portland and still better than Montreal's streets.

5:10 The ballistics comparison is such bollocks. Anyone, if you like that, rather watch the Mythbusters, at least it’s more fun!

germans that fail on building some thiing.. sounds so strange

40 years ago the Ontario Department of Transportation tried a new form of paving on Highway 401 in the west end of Toronto. The 401 through that area is the busiest highway in North America. This new system involved a permeable layer of asphalt that contained ground up tires. Under that later was a foundation of concrete that was sloped to the side, where the water would seep into French drains on the sides of the roads. It worked. The surface lasted for decades. I believe that area is just now being resurfaced. It was too effective and the construction companies do not want to use it. Watching this show reminds me of an old English saying: "An engineer is one who can do for 5 shillings what any fool can do for 5 bob". At the time, a shilling was commonly known as a bob.

in the Netherlands they've used ZOAB (highly porous hot-rolled asphalt) since 1987 on a heck of a lot of highways... water sinks through the ZOAB into drainage systems underneath and next to the highways and the road surface stays nearly completely dry, significantly reducing the chances of aqua-plaining and the chances of accidents due to bad weather... only downside is that, if an accident causes fuel or oil leaks, it needs to be thoroughly cleaned by specialized machines (which takes quite some time) resulting in a road closure during the cleaning process... but there's little to no potholes... (plus, road authorities check the highways daily for potholes, and whenever they pick up on one, it gets properly fixed within hours, temporarily closing that particular lane if needed)... if you don't fix it fast, it'll only get worse... it's as much an issue of material construction as fast and proper maintenance... you can use the best material or construction methods out there, but if you don't maintain it properly, it'll fail just as fast as when bad materials or methods are used...

[@jeffrenman4146]

those guys with the donuts are nuts… Wasn't even a pothole. I don't find this the best series that's for sure

[@samsonkimani2683]

Why do you guys feature bioengineers biochemist neuroscientist 😂😂😂😂 its a civil engineering documentary

[@JAFX1]

They’re funding the documentary 😂

[@egisantoso949]

Research has no bounderies 😂

[@Needles-rx]

Unfortunately it makes the non engineering specialists look stupid!

[@John-nl4lt]

Thanks you’ve saved me time I couldn’t get back 😂👍

Secretly it's skynet

[@weorldedit]

Imagine coming home from building a mega frame using mega bolts and pouring yourself a mega pint of red wine.

[@mtsbr78]

Adoro documentário de engenharia. Uma pena não estar dublado em portiguês do Brasil. Obrigado pelo doc.

[@2moons72]

I love how in Portland, why tear up the street and redo it properly with new gravel and black top when we can just make a new road over the old road. Surely it'll be fine. Then the entire part of the road is spider cracking and the guy says it will eventually become a pothole. But god forbid they'd seal the road, but instead just go out and repair each pothole individually. Honestly a joke.

[@simonstergaard]

boring click bate

[@mickgatz214]

Those 'Mega Bolts' were probably Made In China...😂 As for the Autobahn, looks like a Tofu Dreg Project?...

[@GerBourke]

Building a road on a bog all they had to do was go to Ireland it does not work where is the supposed intelligence and Engineering intelligence😂😂😂😂😂😂

It's only going to take 3 years to finish that Road they built a roundabout near me in Germany that took them 4 to5 years to finish. 😂😂😂

[@dillonbrown8582]

I think this channel is racist, you only feature US Europe 🤔
