Dump Truck @ 50 mph vs. Wall .... ** video with results **

[StageLeft]

That would be a bad way to go.

 

[FrustratedUser]

ouch

 

[Electrode]

:Q

who filmed it and why?

Looks like they're testing the wall

Check out how the cab crunches in a crash, it doesn't look like much effort was put into saving the driver when that truck was designed :Q

Would any car save the driver in a 50mph head on with an invincible wall?

Maybe a few people would get extremely lucky and live, but I'm guessing that just about anyone in any car would be toast.

And hell, I'd rather be in a dumptruck than a civic if those two vehicles were to have a head-on.

for all of you wondering about that wall, it is made of a lot more than meets the eye. i design things like this at work, and the most important thing is what you cant see; the steel. there is typically 3 layers or more of reinforcing steel. the rebar is 5/8" or thicker, and runs in each direction at no more than 14" on center. at the corners, there is tons of corner bars and in this particular wall, it is probably all over the top of it as well. the wall deflected when the truck hit it, and that is what it is designed to do. if it would have sheared or crumbled, the concrete either wasnt high enough PSI or they used the wrong type of steel. the impact force of a truck is not nearly enough to bend steel like that. this was not that impressive and i would have been very surprised if the wall had been damaged. steel enclosed in concrete in multiple layers has a dead load capacity of hundreds of thousands of pounds, so it is about on target for the impact load to be able to take greater than what this truck could exert at 50mph. at 100mph, it may be a different story.

oh, and i would guess it is about 4-5 feet tall, so it is at least 2.5x that underground.


edit: that wall doesnt really look like concrete :Q wtf?!

 

[ReiAyanami]

how about a wall moving at 50mph vs a stationary truck

 

[HomeBrewerDude]

heh good engineering.


the trucks center of gravity was above the height of the wall tho, so a lot of hte energy was deflected rather than absorbed. Plus some energy was absorbed by the ground behind the wall. BUT the wall didn't break.

i saw a wreck in milwaukee where a similar truck with THROUGH the highway divider. The divider was sheered and the truck flipped and ended up on the other side of the median. NASTY carnage.

listen to that whine

Poor test of a wall. Im guessing it is a wall intent on stopping a run-away terrorist or the like. That hopper was empty. A smart terrorist would load that thing full. 3x the mass and you would make a whole mess of that barrier.

What does that have to do with this thread?

Nice video tho. Love that whine.

terrorists usually use small cars and pickups.... besides it would most likely explode on impact with the wall....

Whoa! Thats a quality wall.

 

[BlamoHammer]

Wow...gives new meaning to the phrase "stop on a dime".

 

[zimu]

holy crap, thats nutts.

 

[conjur]

bah....that's old...several months.


Still way cool, though.

 

[Triumph]

Spectacular!

Here is WI we actually had a dump truck blow a tire and fly through the median baricade on the freeway into oncoming traffic. It was a mess.

 

[Actaeon]

Holy!

Wow, that truck got OWNED.

I seem to remember that, but I also remember that truck that had a wheel come clean off. Just driving down the road and it looses a wheel?!

 

[TheBoyBlunder]

That's a tough wall.

 

[Amused]

My GF says arguing with me is just like that.

 

[Analog]

strong wall.
