I love **LOVE** how this is anti-engineered. It uses the weakest mode for every component.

the threaded rod reminds me immediately of [that hotel catwalk collapse from the 80s](https://en.m.wikipedia.org/wiki/Hyatt_Regency_walkway_collapse#:~:text=Investigators%20found%20that%20the%20collapse,under%20the%20fourth%2Dfloor%20walkway). my engineering teacher told us that one story, and literally everything ive designed since has been over built as fuck lol and I avoid structural threaded rod under 1.5" like the plague so this? this triggers me

The issue wasn't the threaded rod but the way the rod was loaded. https://youtu.be/VnvGwFegbC8 I just watched an video on this last weekend. Edit: in fact the flaw was added by the fabricator to avoid using threaded hanger rods.

Really good video. I've read about the Hyatt walkway disaster before, but the video does a great job of ELI5 the load difference on the upper walkway nuts.


sinister_lefty

Great way of putting it, haha. So true


friendlyfire883

I'm sure that all thread is at least grade 3.


Im1Thing2Do

The moment he pulls literally anything it’s gonna rip right off


chemoboy

It's going to do more than put holes in the bumper. XD


horny_coroner

Propably not if they dont accelarate too quick those spiral rods have a little give. But when you push on brake the trailer will smash back into that lexus.


burlyginger

Pulling anything is going to flex those rods and pull the L brackets inward. Not to mention what simply putting the weight of a trailer on that is going to do. It would more than likely snap from those loads.


horny_coroner

Somedays I feel that we engineers are not needet. Today is not one of those days.


niffrig

7lbs towing capacity.


elf25

It’ll work fine long as you don’t pull anything bigger than a stroller


AnihilationPr0xy

That thing’s gonna snap like a twig. Also I love how it’s a Lexus.


friendlyfire883

So will it be the all thread or the 1/4 20 bolts that give out first?


mewhilehigh

I’d wager the rod just snaps under the side load.


meeranda

Oh no. That’s not how hitches work.


Blackcatblockingthem

I feel like I could bend this just by pulling it...


K80Bot

... until he tries to tow soemthing qnd rips the whole bumper off.


bradyleach

I hope it breaks before he gets into the freeway.


Nos2_50

Towing capacity of 15lbs?


MightySamMcClain

Even tows 54 pounds!


ubermeisters

Nice 50lbs shear pins


NotANexus

What is he planning to tow? A tricycle?
