Can a Civil Engineer weigh in on this?

Oops, the third.
No.
Really people, STOP.
A truss bridge is made up of components that connect to other components at each end. The vector sum of the forces at each of these connections MUST BE ZERO otherwise, that connection would be moving and take down the truss. When the ship hit the bridge stanchion, that immediately caused these force “balances” to become out of “balance” meaning that in at least one connection point (and probably many in very short order), the vector sum of forces became <,> zero. Note in the video that the mid point of the larger span was the one that collapsed first. It’s probable that the connection at the bottom/mid of that span had its vector sum changed due to the impact. Once that happens at a point, other points are sure to follow.
LOL! I’m not a civil engineer and don’t play one on television
No matter how absurdly idiotic a thing I suggest as a cause, in the name of satire ... some decerebrate blockhead will take it seriously.

100% Correct — Basic 1301 Freshman Physics!
The Francis Scott Key Bridge. Building 7. You know, the thing.
I’m not a civil engineer and don’t play one on TV. Interesting 🤔

Somebody asked a question. I don’t see anyone replying that it was a planned attack.
Only a Moon Landing denier could post such insane drivel.
Did anyone also hear it was a “nano nuclear bomb?”
Fudd’s First Law of Opposition (”If you push something hard enough, it will fall over”),
A moose bit my sister once. Then he went and knocked down a bridge.
Any freeper engineers out there?
I just do electrical calculations and conduit bends.
Did the bridge collapse move your cheese? Upset your viking kitty? Seriesly?
If you look carefully at the footage, you can see the head of the Lockness monster bottom right.
If for nothing else, this thread taught me a new word today.
decerebrate
Thanks.
LOL! I’m not a civil engineer, but am a software/electrical/RF guy. If we’ve only gone 380 miles up and can’t get through the Van Allen Belts without radiation damage, how did we travel 470,000 miles round trip…without refueling? In engineering, you fail 100 times before something works part way
