Not do be a douche here, but he could have easily made the bridge support all his weight without the towering additions. if he utilized the multidirectional peices more and made "X" beams with multiple beams between each layer he could have made a flat platform that would have supported up to 2000 LB's WITHOUT using plexiglass OR using giant towers.
howard baxter let's be honest with ourselves. Without the plexiglass his foot would have punched through the bridge an it would have failed. K'nex can't take the pressure when it's that focused. It's the equivalent of putting snowshoes on.
The plexiglass just took the place of a large flat knex piece (which they don't make) The plexiglass was supposed to be the steel panels that are laid out on top of the frame before the blacktop is laid.
The bridge eventually collapsed under my weight due to fatigue of the material, but ya, my fingers did get very raw in the 3 months I spent building it!
That is allot of parts, is the plexiglass considered a K'NEX part? If you had more parts, you could use small rods instead of bigger rods. I made a small platform that was 4 inches thick and it did not break on me when I stood on it. I weigh more too. The only thing is that it is much harder to take apart.
It was only a platform to stand on the size of a scale just to see if I could stand on it without it breaking. I can't get over how many parts you have! I have a rubber band ball that weighs a half ton that has been sitting in my garage for 12 years! I can't find someone to display it so I can work on it. I should turn it loose!
Plexiglass true. This bridge structure would not qualify as an all K'nex pieces structure if he wanted to get in a Guiness Book of Records, but it is a pretty cool example of using something simple to accomplish a more complex job! Building pieces with such simplicity SHOULD play a role in the human colonization of Mars! Seriously. If one small piece fails or gets damaged, remove it, replace it, and carry on! Universal sheets and girders, snapped or bolted together, are easier to manage than entire prefabricated girder spans, walls, floors, etc.! I predict here and now that Gorilla Glue and Gorilla Tape (3x stronger) will be used on Mars one day! ~ And if these aren't, what an incredible product endorsement "fail" that will be!
Oh my gosh that things amazing so how much did it eventually hold. This video needs to be see by so many more people I give you so much props for this I can't imagine building this because I know eventually your hands get raw and it just hurts. So how long did it take to build
Try making a Rube Goldberg Machine that goes from the second story ceiling of your house, travel through every room of the house, and end at the tip of your driveway. It is definately not a task for kids!!!
definitely sounds like a challenge! And I do love Rube Goldberg machines, however im a bit busy finishing my undergrad right now. But maybe in a few years!
Very nice bridge. How much did it eventually hold? Check out my ball machines on my channel. They use almost the same supporting technique. The beams on my ball machines are extremely strong.
Pretty cool. But I feel the plexiglass is cheating. Sure it will help his feet not go through the cracks, but it will also greatly disperse the weight across a larger area.
Yes, how abhorrent of him to momentarily interrupt their mundane suburban solitude. He is probably out there every night wooping away at the incessant completions of his Kinex civil engineering projects. God only can know how they can stay focused on America's Got Talent with that inane pandemonium happening outside.
The Plexiglass probably did a fair amount of the heavy lifting as far as distributing much of the weight to the Knee members... Plexiglass in modern times is VERY strong. Some styles are 500x stronger than glass in certain stress case scenarios. Thats what hey use it on the fromt of soda machines etc to withstand the public abuse machines get.
Well im still in highschool and im in pre-engineering but i plan to do mechanical engineering because i just find it to be more fun for me im not sure were i want to go to college but im going to look around you can kind of tell want to go into mechanical engineering just look at my videos i love building hopfully the most efficenty trebuchet or catapult in the world because i compete in punkin chunkin and one day i want to hit the mile mark that is so elusive.
You can join knex in a way to make a flat part, If he had done that till it was about 3inch thick like a plank of wood it would have been more compacted and would not of broken, in fact it would have been more solid than wood. Just saying it was a little over designed. But still nice.
+TheaDragonSpirit it would of bent each of those little joints has a little play in them infact if you take say 10 meter long strip you could actually bend it atleast 45 degrees thn the conectors all pop out there sockets you could make flat parts but then youd have to do some complicated engineering on that also
all of these people are saying he cheated with the plexiglass.. but he could've just made a sheet using the white circle knex and the green connecters and it still would've worked, it was just for convenience
Knex doesnt make large flat pieces, and if he made a deck thick enough for him to stand on it would have been to heavy for the bridge to support. Bridges built in this fashion do the same thing he did, they build a frame out of steel, then lay flat steel sheets across the bridge to make a deck. If you removed the deck from an old bridge you would see that all there is under that steel plate (the plexiglass in this bridge) Is a steel frame. this is dune because it saves weight meaning the bridge can safely hold more weight.
WOW, um, you make bridges and I make K'Nex coasters. Now lets swap challenges, I build a bridge and you build a huge roller coaster, tell me if you quit :D BTW, nice job, I gave you 10 more views for you!
very cool. i think the plexiglass part is cheating. he should of made the deck better so you could walk on it. plus WHY NOT show it collapse as you jump on it in the middle! now that would be entertainment! splash!!
The plexiglass is not cheating because his bridge is just the framework, which is how they build bridges like they, they assemble the framework then lay a deck across it which is usually steel plates covered in concrete or blacktop.
+ Nix Ryu The Sergal Nix Ryu The Sergal no, it's still cheating. It's spreading his weight out across more points. It's no longer just a k'nex bridge. By that logic, he can fill it with concrete, and claim it still counts because he built the framework out of k'nex.
No because bridges arnt filled with concrete, not the old ones at least. But they ARE covered in steel to spread the weight of heavy vehicles so that an 80,000 lbs truck isnt putting all its weight on one I beam
Yeah, that's how bridges are built.... engineers build a frame with lots of holes in it then lay steel plates across it. Has nothing to do with whether your stupid or not.
I love your description of the risks and dangers if it fails...so vivid
he knows the dangers, so brave
You'll put an eye out, kid. 😉
he made that sound like he was a daredevil for attempting to cross it
Andrew: Yes I'd like to buy all these knex pieces please
Cashier: that'll be $30,000 please

Alex Eaton just wondering if you forgot you left this comment
The magic of engineering!!!
what was the maximum load for the bridge
100000000000000000000000kg
Pause at 0:24 for humor.
Adam Martinelli amazing

What am I looking at? The guys stoner "I farted" face?
the girl has a lip thing going on, if you pause it just right moment

Wow this was made 2010 and it’s still the strongest knex bridge I’ve ever seen
2012*

what are you waiting for?
That's not being a douche. That's giving constructive criticism. It would be douchey to do something like call him an idiot.
Like Mike said, that's not a douchebag statement. You would be a douche if you said that the plexiglass is what made it work so he cheated.
howard baxter let's be honest with ourselves. Without the plexiglass his foot would have punched through the bridge an it would have failed. K'nex can't take the pressure when it's that focused. It's the equivalent of putting snowshoes on.

have u got the instrction booklet for this
lol, yaaa....it was my disclaimer incase someone attempts something similar and does hurt themselves.
Amazing build! If you need parts, check us out, we have any Knex part you need!
The bridge eventually collapsed under my weight due to fatigue of the material, but ya, my fingers did get very raw in the 3 months I spent building it!
That's amazing! Great job

Brandon Cunic how long was it though? Did it span the same distance as this one here?

Anyone could make a bigger and better one. You dont know what talents people have. But i am still goddam impressed.

Nice job man, the suspense was overwhelming while you were walking across the bridge.
you`re right, i could have built a bridge deck out of k`nex, it just would have taken a while. But thanks for the feedback!
i got so hyped when he made it to the other side keep it up man!
Go sit in your jail cell sir
Sweet! I build K'nex roller coasters :)
Nice job! It's amazing. :D
Try making a Rube Goldberg Machine that goes from the second story ceiling of your house, travel through every room of the house, and end at the tip of your driveway. It is definately not a task for kids!!!
That's INSANELY AWESOME!!!
definitely sounds like a challenge! And I do love Rube Goldberg machines, however im a bit busy finishing my undergrad right now. But maybe in a few years!
thanks man! I checked out some of your videos and looks like you know k'nex pretty well!
Love it!!! Way to go Andrew!!!!!
What were the results of weight capacity?
what program did you use
I am not sure how nuch danger you were in of breaking your neck or getting stabbed by high velocity k'nex pieces..lol
Why did it have to be over the pool?
No way! Where? I'm at the University of Ottawa for Civil Engineering! One semester left!
at :35 it shows papers. was that drawings you did your self
Cool bridge it's just goes to show that your toys can be useful if you have a vision.
I'm so glad regular bridges aren't made out of k'nex
Very nice bridge. How much did it eventually hold?

My 4 yearold just said "That's awesome!" He is getting Knex for his 5th birthday; the 70 model set. :D
I make Rube Goldberg Machines. One of the hardest challenges on this planet.
This deserves WAY more views! That's awesome! However, wouldn't it have been stronger to use blue connectors and green rods to make a stronger floor?
Adds a lot more unneeded weight, possibly requires all other parts to be stronger and heavier to support that extra weight.
Is that Elon Musks illegitimate son
4:36 I'm sure his neighbors really appreciated that

It's easy to say it could be made less complex. Don't do it unless you can actually show that it is, in fact, easier.

it would have looked pretty neat, especially with one of those fancy slow-mo cameras

Seems like his feet would have broken the through the pieces if the plexiglass wasn't there! But very well done bridge:)
Well done you made it omg
my mom is gonna throw a bridge party. we got doritos cause theyre like the triangles i lernt about.
Congrats sir, you are an official Badass Andrew M.
Thanks Mark!
Now make a knex coaster you can ride in :)
I can't stress enough how many views this deserves...

And then the supporting structure of the bridge would not have been able to support the weight of the deck.
The plexiglass helped a lot tho
the plexi glass changes the way his load is applied....
That kids fingers though, raw i bet
For the design? I didn't use anything. It was all in my head.
AMAZING!!!
That is amazing
I somehow came from MegaStructures... you must have done a good job.
*watches the video*
*B O I*
all of these people are saying he cheated with the plexiglass.. but he could've just made a sheet using the white circle knex and the green connecters and it still would've worked, it was just for convenience
Yes, but then it would have been a true k'nex bridge.....
Nice very cool
its funny you say that because i am trying to go into a mechanical engineering
WOW!
yes indeed
HOLY SHIT MAN!!!
i find that any knex creation with the use of anything else is cheating though i dont find that overclocking the engine is

BTW, nice job, I gave you 10 more views for you!
Sweet
Yea sure man
hear that..but it was a great build though....
Aww i wanted to see him over weight it to see how strong it actually was.
600th like
He's smart
very cool. i think the plexiglass part is cheating. he should of made the deck better so you could walk on it. plus WHY NOT show it collapse as you jump on it in the middle! now that would be entertainment! splash!!

Bridges have a flat area on top for vehicles to drive on. This bridge with a flat surface is essentially the same thing.
Real bridges do that with layers of concrete, steel, or blacktop on top of the framework
Noice
Do u think I'm stupid? The plexiglass evened out his weight and was much easier with that that
Yeah, that's how bridges are built.... engineers build a frame with lots of holes in it then lay steel plates across it. Has nothing to do with whether your stupid or not.
good build though...
This is really old
