"We don't have time to discuss them here" Do you have something else to do? because I'm open for a longer video.
Time and the world as you know it has come to an end. Was it not your sin trapped the unicorn?
Syd G sounds scary, but I’m in the tire recycling business and up for a challenge! 😂
He had a retaining wall to build. He had to go!
Yep. Maybe because I already know a fair amount about the subject, but I thought it was pretty lightweight. Tried to put myself in the place of a high schooler (of which I am the parent of one) and I think they would've been bored too.
I wonder who the intended audience is?
lol. That's what I'm wondering. Maybe he's in a hurry to get home to his wife before Enrique gets there.
Why yes Mr. Algorithm, I did in fact want to watch this.
ciknay lmao, same thing happened to me.
*You're both welcome.*
Thank you that has made my midnight
Who else is watching at 4am when this was recommended..?
Yeah... scary! Me too!!
Make the shape an upsidedown T shape. Checkmate.
That's just a waste of materials. You won't get significantly improved performance.
RTYB its a joke :/
@@RTYB yes you will. In this example, it's clear. An invert t-shape is MUCH harder to overturn. Just try it yourself and see. And I'm only talking about this model, not real world construction, obviously. That may or may not work in the real world (different materials, etc.)
@@visualstudiosproductions Sure, it does. It shifts the toe further from the weight, making the moment arm longer, does opposing the overturning moment (called righting moment). But, if you had to add that piece of wood, it is better to just put it on the other side, extending the length of the horizontal leg. The results are better, I did the math.
It actually have been used in real world.
I can feel the urge to know more about retaining walls growing inside me by the minute! Don’t you ever starve the mind of a professional procrastinator!
Am I the only one who wanted to see the L facing the marbles without the additional friction?
possibly! XD
it would just slide like shown earlier- kinda pointless to see exactly when that is when your goal is to build a functional retaining wall
There's no time for that here.
it will slide too
@@AndreasChristianto Yeah, I was just hoping for a direct comparison but they included the friction pad which ruined it
@@rogerscottcathey lmao 🤣🤣😂
I love the Engineering behind all structures. From basic engineering to the extreme complex engineering.
I lose track when it gets Into deep equations, I get a lot better understanding by watching videos than trying to read the equations.
Thanks, keep going with even more in depth videos.
i'm on the practical end here; i build them.
when you make a retaining wall you would increase the length of the
L leg with increasing the height of the wall (as said) ALSO you make the L leg thicker
both of these will counter the tendency for overturning or collapse of the wall.
if the wall is over 6' we normally will have some footing extend past the vertical
part of the wall (like a upside down T)this moves the tipping point 'Q' further from the vertical leg and increasing the stability of the wall
Cool, thank you. I was wondering asblout that!! So the T shape does work on both issues!!
Wrong
wowiezowiepowie can you tell us about utilizing different/lighter materials between the wall and the land being retained?
@@freeaudiobooks7469 Not helpful.
Free Audio Books your one word reply speaks volumes of your lack of understanding of the problem.
I love this video. In my engineering class, our lecturer explained this so badly. The class was pissed off by the confusion. This video is visual imagery of models made it explain clear. Awesome.
Where has this channel been all my life? Awesome!
As a designer of bespoke rental properties, I love these videos. We always wonder these types of questions when building and just end up testing both to see which ones better over the long haul. In these videos, you do the research for us. Thank you so much!
So you guys are busy building and every now and then you're natural curiosity ends up demolishing another construction site?
Are you on fixed salary or piece rate?
@Swat Are you really a "property designer" who finds engineering solutions via simplistic marbles and plywood videos? Do you work for your dad?
@@waynebrinker8095 what's wrong with working for his dad?
You should hire an engineer. These are not just research, these are established principles that we have studied and every engineer should know.
This channel randomly appeared on my feed. And I’m glad it did!
*Clever engineering* that helps to build our infrastructure.
A lot of nice and honest work in this industry.
great video! thank you!
I think we can all agree that this is one of the best L shaped retaining wall vids on youtube. None of that H or S or even T shape bullshit here
TATERTOTS JACKSON Sphere-shaped walls are the best if you keep the water inside.
Yes, this videos lacks a bit of practical use.
I am persueing engineering and I am glad that I chose the ryt option in the beginning itself !
Realizations are something which keeps you motivated!
this channel is extremely underrated, should have a million subs.
Very useful in determining how I'm going to construct a retaining wall on my own property. Thank you!
where have I been for the past 3 years - thank you, good work
After a strong diet of memes and funny videos, the algorithm still was able to figure out I'm in fact an Engineer
Thank you so much!
Your videos are GREAT!!!
It’s a Sunday morning...I’m not a landscaper or engineer and here I am glued to my screen on the edge of my seat watching a video on the physics of a retaining wall.
Really interesting and artistic way of getting the point across!
Good job mate..
GREAT SCOTT!!! how in this world have I found this channel ONLY TODAY???
Thank you for your precious content. This is PRECIOUS!!!
Greetings from Portugal.
Thank you......The video was very much usefull and simple
You will make common man with good civil engineering aptitude. God bless
Dude you are awesome. Its so easy much easy understand the engineering concepts. Thank you for your effort.
Don't know why this channel stopped posting, videos are good, easily understandable
I'm so happy I found this channel!
Great video.... I would love to see more retaining wall models... like gabion wall, buttress wall etc.
I've built a few retaining (gravity) walls in my time but I'm finding it more and more difficult to find enough marbles for back-filling. They come out through the 'weeps' in the wall too. Could you suggest an alternative?
Can anyone point me to a video about retaining walls that DOES go in to depth about the subject of retaining walls?
There are lots of them, but in lecture style. These are helpful during college days.
Try practical engineering
Dont think he has a video specifically about this but he does a good job explaining engineering stuff in a fun way
A fluid mechanics book will help. Look up forces on submerged surfaces
I do not have time here to send you a link of such a video... haha
Design of concrete structures 13 th edition by Nilson
I always heard about a "heel and foot" in building a wall footing, where the the load side is the "foot" and a short "heel" also extends away from the load side -- like an upside-down T but with one short leg. It is more concrete of course -- but is that design preferable?
Oh wow this was one of the best videos on retaining walls.
You should link the extra videos in the description. Makes them easier to find and follow.
Brought back the final paper of my soils engineering elements vividly to mind.
Selected all three of the values from the Terzaghi curve from the bottom line (engineers will understand this) and proudly announce the retaining wall was going to fail in overturning.
It didn't, I did, along with two other students who made the same mistake.
In the pub afterwards our lecturer, who had been walking the room invigilating, said he'd spotted what we'd done but couldn't say anything.
We were allowed to resit the paper and move on.
I am an architect and I really love your videos! Good job keep it up :)
@Syd G I had structure lessons during my studies and I saw all of this but never illustrated like this .. I think I would have done better in my exams with illustrations of statics like this. This kind of video should be shown in university.
@Syd G I mean it's basic statics... I'm sure it'd be a waste of time to spend any amount of time on retaining walls if you already know how to calculate allowable and actual moments.
I am a beach bum, but this kind of video still releases dopamine and keeps me from thinking of the meaninlessness of life and suffering for a minute or two. Plus it's way cheaper than heroin.
I love this explanation, great examples 👌
Short and sharp! THANKS
Very carefully made video. Thank you!
Simple and informative. Subscribed.
Have I really gotten through so much of the entertaining content on UA-cam that I'm now watching retaining wall videos just to pass the time? I guess so... huh
THANKS GREAT VIDEO YOU TEACH US IN A SIMPLE AND PRACTICE WAY.
I'm not engineer but this was so damn obvious and logical
It pissed me off bc i felt like I was watching a vid for a 4 year old
If you think about it, a LOT of civil engineering principles are obvious through simple logic. For the math to really stuck in the mind, we had to fully grasp every aspect of this simple logic. You'll be surprised by how many huge and complicated structures are backed up with REALLY simple logic even for kids. Don't underestimate these explanations, because these can change a civil engineering student's semester.
@@seriyooow310 I completely get that, I just thought making a video about this and showing such a simple concept that I think anyone should understand immediately is useless. Especially since at the end they don't want to go further with the explanations of different walls because "we don't have time"?
r/iamverysmart
The best solution to a problem is usually the simplest one
This was the first video of yours I have watched. It was great 👍. The binge begins
As my MIL's family would say, "Oh mine too." Glad to have found this channel. :o)
Same I loved it! The kind of casual education in engineering I need!
This is the type of video that excites others to get into structural engineering. I know nothing about it but would have loved to learn it and practice it.
This is some fine stuff right here, mate
Great explanation of how the forces acting on a retaining wall work under 5 minutes.
So fresh and nice when the algorithm suggests something like this. Thank you!
Awesome video! I wish I had these videos during college
I mean this was the 1st video that caught my eye and now I'm dying at the end!🤣
Thank you, great explanation!
Good information!
Thanks !!
Well explained. Thank you!
Liked, Subscribed and Commented... I was searching for a video that would help me visualize and understand retaining walls, I suppose a genie nearby was listening and granted me my wish. Amazing Video Keep it up !!
Thanks you. This is very helpful. Keep up the good work.
John Rex Alegria it’s thank you with no (s) on thanks you ........
It's very useful information for me!
Thank you UA-cam!! -__-
Wow! Great explanation and interesting channel. Thanks! Subscribed 😉
OK first of all why am I here and why am I watching this at 5 in the morning
I have often asked myself the very same question, although as often as not, cute baby animals were involved.
You never know when you you have to build a retaining wall. Better be prepared:p
im here 2:05 in the morning
this series is very useful. thanks
That is so cool. It is the same principle with many bookend models.
Best practical video..👍
Excellent video!!
Most useful resource I could find so far!
Hey that was simple and cool! What about the best of both worlds, an inverted T retaining wall?
A T footing would require more leverage to overturn and provide an increase in friction capabilities. Excellent point!
Pretty dam interesting.
Thanks.
Its very helpful.. thank you!!
What if there is no room for a heel because of the hill? and I need a wall about 3.5 to 4 meters high to get to the ground level. Any ideas? Thank you so much!
Damn I wish schools were teaching like this!
This is what i was looking for. Thanks sir
Excelent explenation!
Yes, we have the time! And we will be discussing them here!!!
Nice video to use an inverted wall you have to check if the soil pressures are under the allowable limits this type of retaining wall has problems with compression of soil failure.
VERY INFORMATIVE AND CONCEPTUAL
Certainly helps with my construction management subjects 🤣thank you UA-cam recommendation
Grt... grt grt.
Loved it..
I dunno why youtube recommended me this vid, but I enjoyed it :)
Best u tube channel
yes but how does the outward bend preform when partially buried? the models you display only show surface performance. i bet the outward bend would perform better in keeping the wall leveled even trough it technically may not bear a greater load
Se puede incrementar la resistencia al deslizamiento de un muro añadiendo un dentellón en la base. Y es interesante señalar que parte del peso que deben soportar los muros de contención sirve también para darle estabilidad si se acomoda la geometría de forma adecuada.
Why you guys stopped uploading content...it is so good and you have good success too with this UA-cam channel.
What about a T shaped wall? Will the horizontal bit be shorter than for an L to withhold the same pressure? Or a cross.. so the sum of three lower bits vs one of L?
I support this channel. Please do engineering model on retaining wall with counterfort model.
Awesome work
Thanks for making this video which is so useful
Супер, дуже доступно і наглядно. Велика вдячніть. Підписавсь, буду спостерігати за вами.
Can I use certain portion of the clips in my video describing retain walls in my native language?
Does water pressure exert on retaining wall constructed along the river?
brilliant video .. thanks
This video really is beautiful
interesting.... Dead man Wall also a good design for retain pressure.
Geogrid mat is more easily incorporated between courses and material doesn't degrade
I'm convinced it's a major contribution to road safety
(Timestamp: 2:30) My answer: I went with the "pointing in" wall (right) instead of the left wall at first. My reasoning was that the marble's weight would push down on the wood sticking inwards and leverage the wall to stick upright longer from the extra force.
Edit: I was close- I used improper terminology and worded my response weird, but I had the general idea down. I also didn't realize that the downwards pressure would also increase friction! That's a key detail to miss. Close, but not exactly. 3/5.
So creative explaination👍👍
Cool video liked and subbed👍
i knew it
the right one
nice one :3
We are just scratching the surface here but great video. Engineering is fantastic
Do you have one on roof slabs, depth of concrete and span?
So would an upside down T shape allow it to be steonger?
Suicidaljello yes
@@silentwatcher1455 Sometimes u dont have enought space to make T form of wall or u spend concrete no need.
It’s not difficult to make a retaining wall stronger. The trick is to have it support the load at the lowest cost.
It’s called a BUTTRESS.
It would look stupid having the T exposed, you would have to bury the horizontal section so it doesn’t look stupid.
Prof:"We don't have time to discuss them here."
Me: Now I most certainly do. 😷
