Good point, we wouldn't want to melt the special little snow flake if he were to venture outside his safe space.

G'Day mate.

Despite overwhelming evidence, apparently if you don't believe this video, you have a "conclusive file". I wonder what he believes the actual failure was? He doesn't say after hundreds of hours of previous videos. All as we know is that he believes it was not a horizontal interface shear failure and you are an "idiot" engineer if you don't believe what he believes. I would love to see the numbers and evidence to indicate another possible failure mechanism. I am truly and honestly open to any scientific evidence that shows another plausible mechanism. To date, I have seen nothing credible or even any failure mechanism presented on the YT channel.

Six people died and one person was severely injured. I only comment because someone is using pseudo science to promote conspiracy theories and personal agendas on their YT channel. Science maters and the proper use and evaluation of evidence maters. When you see pseudo science used to promote a false agenda, it is up to the rest of us to call it out. The victims and the public deserve better than this.

If you don't understand basic concepts like vectors, static, or that gravity generates a load, then you need to read up on the science and learn some of the fundamentals. The YT presenter believes it is "equilibrium" that generates the forces and not gravity and if you don't believe that, you have a "conclusive file". He has a different definition of equilibrium from engineers but he doesn't describe it or tell you how you can use it to calculate forces, stress, deflections etc. If you can't take science as a foundation for discussing or evaluating such an incident, then there is no hope in ever determining a likely cause to an incident and we learn nothing.

I invite the YT presenter to use science to describe another feasible failure mechanism and come to a forum like this one where it can be scrutinized. All scientific ideas need to be scrutinized. Being shielded on a YT channel and deleting all comments that challenge your ideas, stunts any possibility of learning. Don't be afraid to be wrong, it might hurt the ego but in the long run you will learn more.

I would also like to end by saying something positive. He does collect a lot of evidence which we can evaluate and that is a good thing.

After this 'youtuber' first came to my attention I watched one of his videos...for about 5 minutes...before I realized that this was a big waste of time. I'd rather spend my time, which is limited, on something more useful, like watching reruns of:

Earth314159,

He was on the forum. He started getting fired up over politics; I suspect that's why he was banned. That, or repeatedly calling Eng-tips contributors "idiots" in his videos.

There's no need to mention him any further and instead just stick to relevant engineering.

 

[Earth314159]

3DDave,

That is a good point. I didn't realize he was on the forum before. He is a waste of time. I just don't like pseudo science in principle and call it out because of the damage it causes. You are right. It is best just not to mention him.

 

[Tomfh]

I agree. We will not discuss him any further. We won’t even mention him.

 

[Agent666]

I note istructe video linked to earlier is now avaliable on youtube, as at least one person indicated they had issues accessing it.

NTSB News Release:

The National Transportation Safety Board announced Thursday its intention to hold a public board meeting Oct. 22, 2019, 9:30 a.m., to determine the probable cause of the March 15, 2018, FIU pedestrian bridge collapse.
