Are they pants or shorts or jorts or the kids pants

Atta boy! Way to lift with your back. Strongest muscles in your body...

Looks like the kid knows what he's doing and dad is following around. Brillant kid

I had a hard time watching this due to the mouth breathing retard holding the camera.

Does that kid even lift? Such bad form.

@OP, the real challenge is to build a Leonardo DiCaprio bridge!

Lovely, now build an Einstein–Rosen bridge, please

And for easy carrying, turn it into a Bose-Einstein condensate.

This is what (potentially ) keeps kids outta prison and of the heroine. ..

When I was a kid I always wanted to be in the heroine... still do.

I wish my co workers were as useful as that kid.

What an awesome activity for a kid love it
RonaldFckingSwanson
What happs when he cant lift it up anymore?
bicflicker99
Longer boards for more leverage, or some kind of mechanical assistance.

Cool thanks!
ErinFromTheOffice
If you try this this, you might want to notch the 2x4s. Otherwise it all relies on there being enough friction from outer dowels to not move
WHOLEMILK
I thought the same. I figured the pieces were going to spit out when the kid walked one. You notice daddy did not walk it. very cool
GenerallyKenobi
Technically only need to notch the ones on the end
maybecrazy
Isn't that part of the point?
ErinFromTheOffice
Friction is a property of the wood being used, not the design. And Da Vinci probably didn't use perfect 2x4s or perfect dowels.

Wood grows with friction

FreeHandBrain
Kid needs to make his step-dad work harder if he wants to bang his mom.
deflationary
...did I miss something here?
Zero3Quarter
At least the kid was doing the lifting. Nice to see a kid working hard on something like this.
Flyndaran
Nice to see outdoor activities, but those are wood not lead. So working "hard" isn't how I'd put it.
SubZeroWithAFever
I bet you also think the dad's choice in pants was a good one too huh?

It's a KID!!!
Flyndaran
Kids aren't jellyfish. They have muscles. My number of down votes must say something about how incredibly weak most of you are.
shveet
there is a Popsicle bridge competition at my college for the engineers... i kind of want to build this now, see how it preforms..
coutod
I'm good friends with the guys who hold the max weight record at that competition. From McMaster.

HitlersArtCritic
Maybe just stack tons of popsicles together as thick as you can, using a simple design. Saw it work in a competition hold more strength than
HitlersArtCritic
Other bridges despite the weight as its just |-| and not doing the usual thing, Triangles everywhere.
profinger
It's not going to preform you're going to have to form it yourself

I'm really interested in this, would you make a post about it?

ElOsOPoderoso077
My college too!, mine held 700lbs, 37 tongue depressors, 2 hot glue sticks, DM if you want the specs and maths @shveet
ElOsOPoderoso077
Also im the new record holder at my college, beat the other guy by 150lbs
rubbarz
It being Leonardo DaVinci this shit could probably hold a tank.
callmethelizardqueen
When in HS I entered in a state wide bridge building competition,came in 12th out of ~1,200. Teacher still didn't like me.
probablyobvious
When I was taking engineering we did the same thing with spaghetti and hot glue. Mine held over 314 times it own weight before coming down.
TheLazyLibrarian
I did it with popsicle sticks and rubber bands before in high school. Honestly not sure if a single popsicle stick would've done the same.
Trecares
So it held a pies worth of weight?
probablyobvious
You know, I never noticed that before!
genderassumer
Damn! My 250g spaghetti bridge held like 11kg before it snapped only because I coated that thing in epoxy
yuyufan43
Gotta ask... since it's already been designed, isn't that kind of cheating to put it in the contest?
ElOsOPoderoso077
I don't think this will qualify if the competition states it must be a truss bridge
yuyufan43
Oh, ok. That's interesting. I was honestly just curious on the rules. I'll have to look up truss bridges! Thank you! :)
PuddingIsAmazing
my school had a balsa wood bridge challenge, and I made a bridge that would collapse without breaking so it technically would support the(1)
PuddingIsAmazing
weight for the challenge. I was the only one with the idea to make axels entirely out of wood, and the teacher allowed it for kicks.(2)
PuddingIsAmazing
on the way out the door on the last day I tripped and fell and it shattered. Middle school me cried so hard. I was so proud of it. (3-end)
SilverEtchegaray
Here. Give one of these to middle school you next time you're time traveling. You can keep the other one.
PuddingIsAmazing
I had to re-read that. your sentence fucked with me
diamonds5022
As a person who did this in High School, wood is strong under compression not tension, and trianglular shapes are your friend.
ElOsOPoderoso077
Actually it's the opposite, we've tested tongue depressors at my college with a strength machine ,tension is like 3x stronger
redsilverchum
You could build it just for the experience, not necessarily to win, since everyone is talking up the trusses.
MalthusAndreusDrake
it's not the strongest design, but it is very beautiful and does work better than some of the more complex designs.

Kaburleigh
I did this for a popsicle competition when I was in high school. Got 3rd place! It's super strong too
datMaggie
Badly. This bridge is designed to not use fasteners. It is not an actual efficient use of material, strength-wise.
calldrdaley
Fasteners aren't what gives a structure strength...
datMaggie
This bridge is supported by the sheer strength of those dowels. Wood, like most materials, has a far lower shear strength than tensile (1
datMaggie
strength. Most bridge designs focus entirely on tensile strength, with very little shear. Wood is especially bad at shear because of the (2
datMaggie
grain structure of wood.
calldrdaley
Hooray for google. Except we're comparing a structure that is held together by adhesive vs one that distributes the load throughout itself
calldrdaley
(2) Statics is the branch of engineering you should be looking up.
datMaggie
I have a mechanical engineering degree.
spookyu
I'd imagine it has a different application, like as a temporary structure or in the case of limited manpower or time.
FogOfWar122
I believe it was to help soldiers cross streams, but I'm not sure. It'd explain the lack of fasteners, as it could be taken down and reused.
ReallyBadAtImgur
A lot of Da Vinci's ideas looked really neat, but they were just ideas I'd assume. I doubt he was selling these plans, he was just creative.
SpringToMyWinter
Da Vinci was kind of the original genius, so you're probably pretty safe.
Jufasa
DaVinci didn't come up with this but it was written in his journals so they named it after him

Spacebandit
I don't believe he was the original. But genius non the less. His ideas were from birth of renaissance from the East in Europe.
FreeHandBrain
Actually, when he was younger he worked at a patent office and stole most of his ideas from a guy named tesla. History is amazing.

And then he electrocuted an elephant.

Actualy it was Edison that electrocuted the elephant to prove alternate current (by Tesla) was dangerous.

Right, and Einstein worked in a patent office. The comment is a jokey joke mish-mashing different people.

hugh705
Horribly, the dowels would shear before there was much of a load. Just go with a Pratt/Howe truss for simplicity.
probablyobvious
Fir has a max shear strength of 1,500psi. Looks to be 1/2“ dowel in double plane shear. Totalling a max yield of 1500lb. P1
hugh705
He's talking about popsicle stick bridges though, I'm not shitting on the bridge in the video. Also you're forgetting the moment about 1/2
hugh705
the dowels, those 2x4s are levers, so a smaller weight could definitely shear the dowels.
probablyobvious
It's a simple supported load, no transfer of moment. It will literally hold its capacity.
probablyobvious
Assuming no safely factor but an 80% reduction natural factors, and self weight ( 100lbs to be safe) I would say it could hold 1000lb p2
turbotricycle
Those are probably pine 2x4s.
probablyobvious
He is literally build a bridge in their back yard with no fasteners to explain physics so that his kid might become interested in it, chill.
SilverEtchegaray
Actually, if you watch the video, the kid is teaching the Dad how to build the bridge. I don't even know the kid and I was super proud! Lol
