I almost never comment on youtube videos, but as a student in an undergraduate engineering program, your video has demonstrated the shear stress, and shear flow concept better than a semester of stress analysis has. Please continue to produce these videos as they are indispensable to the future engineers fundamental understanding of these concepts which otherwise just get muddled and only the application of the math is understood. Great job as always and I will continue to support this channel.
Agreed, i would like to see new videos more often :)
unfortunately it's like you say..
I went through 4 semesters of statics & structural analysis during my undergrad and these models have helped me visualize things more than I was ever able to visualize in the classroom.
Agree, I am from Croatia, same here
Exactly brother even teacher himself got muddled up that's why unable to taught us what does it actually means and how it works
Watching this video was shear pleasure.
yes. so true
😆😂
It needs more support, it's very informative.
Sheer Pleasure
If only for the moment...
I recognized this voice the moment the video started. You were my professor for CIVE 306; easily one of the best profs I've had.
Great
Which university??
Why did you guy's quit making these? THEY ARE AMAZING! And you guys were doing a great service for the curious people of the world. Thank you for them. Please consider making more!
I FINALLY WATCHED EVERY SINGLE VIDEO ON THE CHANNEL
Yay!
I am already an engineer but had forgotten about a good portion of this stuff, helped me remember a lot
Excellent explanation and demonstration! This feels like a lost art since I've seen something like this in the retro videos. Irrespective of whether one uses a physical model and/or animation, a clear, thorough, pedagogical explanation is the crux of such a presentation and you have done an excellent job at that.
Best explanation of shear flow stresses in a beam that I have ever seen ! Thank you.
I miss having physical models in class. This is so much more intuitive!
I sincerely appreciate the effort dedicated to make videos like this. You help students much more than you think.
Where have you been all my (professional) life. This video so beautifully explains what shear flow is, and how shear stresses relate to the bending moment and applied forces.
I have never seen anyone explaining the ideas this simple and easy
I hope you make more videos
and help us understand more.
Everything is crystal clear now... Thank you engineering models 👍
I appreciate it very much Mr. Professor. This is the most elaborate explanation I have ever seen on TH-cam. Thank you for your great efforts.
Best shear flow explanation I've ever heard
If this videos were made more often, this channel would BLOW UP
Very nicely demonstrated..thank you...keep posting civil engineering related videos
This is amazing, wish I saw this sooner and also wish that more people know about this channel.
Absolutely incredible explanation of something that has always bugged me for years.
Looking forward for any updates and growth of this amazing channel. Really helps a lot with the understanding of engineering!!!
I wish I could have had this explanation as a student. Incredible!
Thank you for such an outstanding explanation on shear distribution. It makes my life much easier now 🙌🏻 !
Thank you, you are a good teacher.
Jeez it can't get more clear than this. Thanks a ton mate for your efforts. 😘😘
The best that I found on TH-cam till date. Thank u sir
Beautifully explained! Thank you 😊
I'm in love with your contents. Please create more of these.....♥️
This is trully great! Finaly I understand! Thank you so much!!
Fantastic work. Will be sure to show this to any interested classmates
This is super helping. Thank you good Sir.
Amazing ....one of the bestest explantion on ub tube about shear stresses.in beam. 👌👌
I could feel my brain shear under the stresses of watching this video.
Sounds like your brain is in tension.
Ooo improved model and elucidation, thank you! It would be great to hear more discussion on how this theory relates to / results in failures in some real-world circumstances.
If you are curious, you will be served plenty. There is much more than discussion available. There is too much litterature and research to cite all in here. Practically every country has tons on this subject. First, this video is about strength of materials theory, and in this video it is extremely simplified for beginner students. The theory goes down a very deep rabit hole and can be applied to different materials using their known properties. Every material reacts differently under theses effects. if you are interested in concrete, see ACI (american concrete association) or CSA A23.1 Canadian, steel, see CSA-S16 (canadian), wood AWC amercian wood council US or CSA-O86 canadian, i dont know for Europe, but they have what they call Eurocodes. most of the codes are not free, but you can find lots of interesting pdfs on scribd. Thats where you can find results of research and known failures. There are also chemical degradation that adds to the mix. Engineers who do detective work to diagnose why structures have failed must take all these into account.
Best video to understand Shear in beam
Since I'm not an engineer i could use a few minutes at the beginning maybe showing how this comes into play...maybe showing some beams on a bridge and a truck sitting at a location and how that would create stress on the beams and where.
best presentation ever about shear center
You made me feel the shear stress literally
This was beautifully done 😍, great job.
Your animation always top class
This is the first video produced on this channel which eludes me completely. I have no idea what it's talking about. But I'm just a layman, not an engineer or architect.
wow, thanks for your sharing . clear ,very clear.civil civil engineering.
That's simply amazing!!!
Extremely helpful, thanks
As a carpenter I thought this will be good to watch. Two minutes in, I realised I'm way out of my depth. 😳😂
Its not, you're just missing some background
😂. Nevertheless it's for structural engineering fellows.
This is very good...thank you
I wish I could super like this video. Thank you!
Best explanation of shear stresses
Please make more videos, they are great!
And by the way, the video taken perspective was superb.
Finally I have understood what the hell sheer flow is!!
Great great work and explanation
this is amazing, i wish i had studied like that
THANK YOU SO MUCH. May you be always inspired to do lots of videos. I will give my best support.
Great series of videos!
I woud like to know why engineers use triangles in the strucures os bridges instead of rectangles structures.
great work
thank you so much
This is next level learning
Thanks you tube algorithm. This will surely help me in my career selling fabric
lol
until I watched this video, I could not understand how this shear flow work.
After having watched this video, I think I understood that. So thank you for your kindful video.
This is very stressful.
Of course this video is _ precisely _ 10 minutes long..
Brilliant explanation of the physics here sir.. thank you :)
Now i really understand as to why bending moment is maximum at zero shear. Thanks for this video
Please explain how?
This tutorial is amazing! I propose using magnets to attach the fibres.
will not be economic.
Dude. Im a janitor. Why is this in my reccommended?
so you can be a smart janitor.
So you can thoroughly understand the bending stresses in your mop handle. 🤣
Thank you very much!
Just Brilliant
Goog explain. Thank you a lot!
Hope you decide to make more content sooner or later. Easily one of the greatest introductory engineering channels on YT!
What we got here on youtube is a miracle
Nicely shown that S = dM/dx Shear stress is the differential of moment
You are right!
In simple term:
2 different forces in different plan and in different directions of element cause shear force
Very nice! Thank you!
At 9:50, a correction, at Qf calc... missing the indicator "2" outside the brackets { }...
please more videos, cover the entire mechanical engineering
this is excellent
This is exactly the kind of thing the internet was dreamed of providing and, in the early days, it was fairly prevalent. Too bad now the internet is so riddled with crap.
Thanks !
Very good informative video..please upload morw coneptual videos reagridng civil engg
Jazaqallaha ho khair
Amazing
Very very nice
If shear stress is developed from the uneven bending moments in a beam when loaded on the edge and clamped on the other end.
Does a center loaded beam with simply supported condition on both sides have shear stress then?
Step by step video solutions of civil emgineering questions
your name should be written in golden words in civil engineering history
My dear sir, please make more video. And have a good day..
Please sir more vedio abloaded please abload. your vedio is very useful.
Upload*
It’s too bad they don’t post more often. I would love to see a gear ratio video
great
BUILD THAT WALL BIG BEAUTIFUL WALL
We cant there will be too much shear stress in the neutral axis
Ahh yes, recent comments, it must be finals season again.
استاذ نزار لازم يوخذ نسبه من مشاهدات الفيديو
at 2:22 . How can we treat it as a free body when it is not? Why would the rest of the section try to stop it from moving when they themselves are moving?
best video
So it is leverage in the height and width instead of the length of the object
This is one heck of a zip file!!
Is this transverse shear stress or normal shear stress?
Why two of the faces were not having stresses on them , the top and the bottom , are going to be the two faces where we we
don't draw any stresses. Does each has a stress of Z direction for Normal and shear stresses?
Dos Antoine knows where can i get one of those models?
does anyone how the shear behaves in the very center of the flange? there would be 2 shears on 2 sides, but both points in the same direction? then there will be no shear at all?
At 7:10, the shear along the axial direction on the right should be flipped.
As a psychology student, this is like an alien language to me. it took me half the video to realize the wooden model represented the cross-section of a steel girder.
nice
I did not understand what load is on the beam, in what direction, where, to start with.
0:25 The cantilevered beam of 32 length-units long has a mass of 412 mass-units at P (left end) while the beam is supported (by a wall) at the the opposite end.
The top if the beam is in tension, the bottom of the beam is in compression.
The forces increase further along the beam away from mass P, towards the wall.
P= - 412(down) @ A
start with, watching carefully.
This is a section of the beam. Imagine it as 1/3 of the entire length of the actual beam, and that this section is the center 1/3 of the beam (with an equal sized 1/3 of beam on both the right of this section and the left of this section)
Like this:
(force pushing down
on left side of beam)
______ ______ ______| |
|______ ______ ______| |
A B | |
| |
Wall
The B Side of the entire beam (right side) is connected to a wall and the A Side (left side) is free floating.
Pressure is being exerted down on the beam, with the left side being more affected by the force because its free-floating (cantilevered), as compared to the right side not being affected as greatly because its attached to the wall.
sir,
please do update with new video, which could be anything. I in India need a practical demonstration lectures by you guys.
