They should just sell a shitty social media site instead
Bad deal...

Stating my opinion and defending myself from people attacking my faith isn't trolling anymore than you spewing your opinion.
Pull your big boy pants up mate.

Hahaha.
Derek reached out through PM, and I responded.
I am hoping for a cease fire, so you and Mr. Buzz may need to pick it up from here.

Allow me to diverge from your pissing match and get back to the thread...

I bet the captain of that ship was crapping himself. No worse feeling than having zero control over the one thing you’re supposed to be controlling. I’ve had these sort of moments in my truck. Obviously not near as much at stake, but yeah. Wow. I feel for that guy and his crew

Why does HT have to go to the weird dark side after five posts? (Asking for William Christy.)

Man I'd be real cautious in taking your "news" or "facts" from social media.

However, I did read on IG that Temu lost $6.47 when the three containers full of it's merchandise went overboard.
That is the kind of insight social media is great for.

What you mean you should get medical advice, political commentary, or engineering analysis from the stoner kid who dropped out from HS and has a podcast from his mom's basement?

I am an engineer, although not a structural engineer, I did take all the structural design courses that were available in undergraduate studies because I thought I would go that route after graduation. Lack of available jobs took me a different direction. So take my analysis with a few grains of salt and understand that bridge design is a whole other can of worms.
The bridge failed about how I would expect. The bridge appears to consist of 2 different types of construction. There is the central steel truss section and then on both ends there is a simple post and beam style of construction. It looks like the post and beam sections remained standing. From the photos that google has provided me it looks like the connections on the standing sections are more "fixed" style of connection. Fixed meaning rigid and each span is it's own self supporting structure. The 2 central piers that supported the truss seem to have more of a pivot style connection. The truss section itself acts in a counterbalanced or cantilever manner. Watch how the far section of the truss actually lifts off of its support before collapsing as the bridge teeters on the other central pier. That entire truss section functions as one unit. If the ship had hit the pier supporting the end of the truss it still might have collapsed the whole thing.
As for designing for impact, that may be a newer requirement or the cost/risk analysis determined to design for a lesser impact force. Just like most things that are designed to sustain specific loads based on risk. We design houses to sustain wind and snow loads but we don't design them to resist the force of semi-truck driving into the wall.
I am also reminded of an engineering joke: "Anyone can build a bridge that will stay up, it takes an engineer to build a bridge that will barely stay up."

It will be after the election before the debris is cleaned up and the shipping lane opened up. Full disclosure after I left the USACE I worked for an structural engineering company that specialized in the forensic analysis of structure and super structure failure.

This why most structure codes have 2:1 saftey factor required for design...That impact was way above the 2:1 saftey factor.
