Fun with Arches 

1:30 26 seconds of silence 1:56 "Isn't that cool?" Nice simplistic production, no unnecessary music or repeated conversation to fill the gap :D

Fun with Arches .. why it sounds like another Sheldon's web series?

She was forced to do this for her semester grandes

isnt that coool?

NASA: Has anyone seen the new intern?

She's staring into your soul

Damn I feel ashamed haha, I'm doing a PhD in mechanics-related stuff and I had no idea about this chain rule. It's really beatiful too.

The NASA shirt girl is cute

awesome!

2:03 me irl

The format of this video makes me feel like I'm watching Dora

*THE RECCOMENDATION GOD HAS CHOSEN YOU*

The title and the way the man Says "isn't that fun" reminds me of Sheldon Cooper's "fun with flags"

She wanted to be an astronaut but her parents differed...

This was actually pretty informative and fun!

This is adorable. Thank you.

Just when I thought this channel couldn't get any better. Boom! Cute girl with arches!

does anyone know the assistant instagram, she's kinda cute, just standing there, helping, but not saying anything (according to the credits her name is Zi Yang)

Green shirt asian is that kid in your group that shows up at the end of presentation to get credit for the project.

Sheldon get older and has a new asian gf lmaoooo

YOu say the arch cant hold the weight of 2 blocks then clearly push it down with your hands before you put the blocks on it.

1:56 reminds me of Sheldon's fun with flags wity penny😂😁 Keeping jokes aside I am really happy that i found this channel as an engineering student from the different side of the world where the education system doesn't focus much on explaining but more focused on marks we were able to score

interesting, thin semi circle arch does not work well. Now I'm questioning circular tunnel since isn't it like 2 semicircle?

Wow amazing, not a lot of videos on civil structures on youtube. Thank you very much for making such videos and keep up

I found this channel yesterday and I loved it s2 You are amazing guys. I want to see all of your videos, but I have to work now ;-; haha Really really good. Hello from Brazil!

Yup -she's definitely having fun.

Thank you for the videos you produce. You’re doing a great service for the engineering students all over the world. God bless you all.

I didnt get a thing, she is just too pretty to concentrate.

The girl on the left is sooo interesting, idk why, but she look like smart nerd and some internet troll at the same time. Please don't lynch me in comments.

Now I know what to do when I need those 2 wood blocks held up. Thanx man!

Sheldon´s new hobby, he was bored on "fun with flags".

She cute

*"theres strength in arches"*

very useful channel please give updates

great video, I finally know what to do with my two wood blocks, six oranges, and three plastic containers of marbles!

Supper ..... video is so clear

This reminds me of Sheldon and Penny doing the "Fun with Flag" 😂😂 btw thnk u for your demonstration it really helps me.....i hate dat I came across this channel jst today😔😔 it would be of grt help if I found this channel earlier during my engineering days😔👍👍👍👍👍👍👍👍👍👍👍👍👍

Love in first sight

All the time that I wasted with flags when I could have the time of my life with archers!!

Really good content. All vids need to be watched in 2x speed.

Great video. Thanks from Belgium

*silence* ISN'T THAT COOL?

He seems like a good teacher. I wonder where his assistants are now. Hopefully doing well.

1:28 she was like "I want to see aliens, not this sh*t"

this... this is the best channel on youtube, omg great job. I noticed no new videos have been made in a year, hope you're okay!

This is a genuinely informative, cool, and punchy video. Yet that prof is employing such a stilted, deliberate manner of speaking, that he makes me laugh. I think he is trying to project a detached, scientific, professional demeanour as he delivers some truly cool and impressive demos about arches and chains. His artificial nonchalance is distracting, and I believe that inside himself, he still feels that sense of "wow" and "how cool is engineering when it all works!"

"If it doesn't pass the chain-test, it falls." That _has_ to be a t-shirt!

In my next life (if there is one) I am going to be an engineer. Thanks, I learned a lot from this one.

18 people will be crushed under a collapsing arch.

wow its really amazing 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍 perfect vidoe

00:29 he bend the arch beam by his hand.

2:55 stones 3 & 4 are a split keystone.

İs there any formula for calculate this model i mean how can ı calculate slope thick and more

For some reason, the guy reminds me of old Sheldon Cooper.

The arches are paid actors

Lol when was this video made it has to be from the late 90s. Good information tho

How this remember me SHELDON COPPER?

AMAZING, I HAVEN'T SEEN A VIDEO LIKE THIS

So informative and so awkward 😅😅

You know he's clappin them cheeks

00:30 - watch the left hand of the professor.

Reviewing right now for my board exam and your videos are really entertaining. Simple yet educational. Thank you!!!

" Thanks for watching" so cute~~ awesome video! always amazed with arch structures!

Why my teacher was so boring?

I thought intuitively removing the middle weight the arches would still stand.. But it fell.. Interesting..

You can call me mad by i think it's cool

please make a video lecture on trusses

Wonderful video! Chain test give me a simple easy way to understand if a construction Will be resist or not without matematic....Great!

Didn't builders used to use hanging chains / ropes to figure out arches and forces in their buildings? I remember a photo of Gaudí next to an upside down rope representation of part of the Sagrada Familia.

This reminds me of "fun with flags" by sheldon... But i actually have fun watching this for some reason

This was mind blowing and pretty informative also great fun! love from bangladeshi civil engineering undergrad student.

I’m glad if u recommend some other RU-vid channels like this !! It’s interesting.

Can I please use and share your channel on a video I am putting together?

this is best video on internet the

My boys gonna put your arch trough the chain test 💪💪 y'all ain't ready for this

Reminded me of fun with flags by Dr. Sheldon Cooper

Does the thickness of the chain play a role in the mapping of the arc? If so, what ratio is necessary for it to be correct?

Please do things as you’re explaining them so that theres no awkward pauses in the middle

Interesting, thanks! Was nice to learn all arches don't need keystones :)

So the area between mirrored chain and the bridge acts like a pushing force

"It cant hold 2 wood blocks" (pulls one side down with his hand)

Thank you for this illustrating video.

are they grandpa and grand daughter? they have some similarities !

Sheldon's Fun With Flags was better

I love her

Asian student Like sum ting wong

Genuinely thanks for the explanation like this !!

If keystones are not necessary, why are they used so much ?? 😕

So the chain test also tells you how thick you have to make an arch?

I, too have fun with backs.

Amazing content, and the reading is so natural

very well done how come the cute Asian girl is not smiling ha ha ha

Please make videos on 2 hinge and 3 hinge arches

Really wish you guys would play PolyBridge

Blocks Blocks Blocks

Excellent video very nice explanations

Okay, so how do I hang a chain upside down?

the information you provide is amazing!

That "Thanks for watching" part slightly creeped me out

2:24 no, its cause your holding it mate, same as a hammock that has anchor points on trees
