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.
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
Step by step video solutions of civil emgineering questions
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??
Watching this video was shear pleasure.
yes. so true
😆😂
It needs more support, it's very informative.
Sheer Pleasure
If only for the moment...
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!
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 sincerely appreciate the effort dedicated to make videos like this. You help students much more than you think.
I have never seen anyone explaining the ideas this simple and easy
I hope you make more videos
and help us understand more.
The best that I found on TH-cam till date. Thank u sir
If this videos were made more often, this channel would BLOW UP
Best shear flow explanation I've ever heard
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.
I wish I could have had this explanation as a student. Incredible!
Everything is crystal clear now... Thank you engineering models 👍
Absolutely incredible explanation of something that has always bugged me for years.
Amazing ....one of the bestest explantion on ub tube about shear stresses.in beam. 👌👌
This is very stressful.
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.
Thank you for such an outstanding explanation on shear distribution. It makes my life much easier now 🙌🏻 !
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.
Finally I have understood what the hell sheer flow is!!
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.
Thanks you tube algorithm. This will surely help me in my career selling fabric
lol
Very nicely demonstrated..thank you...keep posting civil engineering related videos
Fantastic work. Will be sure to show this to any interested classmates
Jeez it can't get more clear than this. Thanks a ton mate for your efforts. 😘😘
You made me feel the shear stress literally
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.
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. 🤣
Best video to understand Shear in beam
Now i really understand as to why bending moment is maximum at zero shear. Thanks for this video
Please explain how?
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.
your name should be written in golden words in civil engineering history
best presentation ever about shear center
Of course this video is _ precisely _ 10 minutes long..
Brilliant explanation of the physics here sir.. thank you :)
THANK YOU SO MUCH. May you be always inspired to do lots of videos. I will give my best support.
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.
Looking forward for any updates and growth of this amazing channel. Really helps a lot with the understanding of engineering!!!
This tutorial is amazing! I propose using magnets to attach the fibres.
will not be economic.
This is amazing, wish I saw this sooner and also wish that more people know about this channel.
I could feel my brain shear under the stresses of watching this video.
Sounds like your brain is in tension.
What we got here on youtube is a miracle
I'm in love with your contents. Please create more of these.....♥️
Hope you decide to make more content sooner or later. Easily one of the greatest introductory engineering channels on YT!
Best explanation of shear stresses
Great series of videos!
I woud like to know why engineers use triangles in the strucures os bridges instead of rectangles structures.
Your animation always top class
And by the way, the video taken perspective was superb.
Very nice! Thank you!
At 9:50, a correction, at Qf calc... missing the indicator "2" outside the brackets { }...
Thank you very much for the video. However, I understand that bending moments at A and B are of different value but why are they of opposite direction ?
This is next level learning
Thank you, you are a good teacher.
It’s too bad they don’t post more often. I would love to see a gear ratio video
You are right!
In simple term:
2 different forces in different plan and in different directions of element cause shear force
Please make more videos, they are great!
Step by step video solutions of civil emgineering questions
wow, thanks for your sharing . clear ,very clear.civil civil engineering.
I am confuse.
Why your channel has only 138k subscribers ?
Very good informative video..please upload morw coneptual videos reagridng civil engg
Great great work and explanation
I wish I could super like this video. Thank you!
Please sir more vedio abloaded please abload. your vedio is very useful.
Upload*
please more videos, cover the entire mechanical engineering
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.
this is amazing, i wish i had studied like that
This is super helping. Thank you good Sir.
My dear sir, please make more video. And have a good day..
Beautifully explained! Thank you 😊
This is trully great! Finaly I understand! Thank you so much!!
Nothing is more than this to depict.Its phenominal..
The long term dilemma is ended by this video.no professor can explain this..
Ahh yes, recent comments, it must be finals season again.
Nicely shown that S = dM/dx Shear stress is the differential of moment
This was beautifully done 😍, great job.
Proof that a college education is a waste of money!! TH-cam is free!! Great video!
Simon Leland ahh yes companies should start hiring more TH-cam engineers lol
For sure bro, for sure!
Hey I heard that TH-cam sends in a pHD in the mail after 6000 hours of videos watched.
@@benjaminlavigne2272 I got my YTphD after just 2950 hours. I used a fast computer too.
@@mccc4559 lol
great work
thank you so much
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?
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.
Thank you very much!
sir,
please do update with new video, which could be anything. I in India need a practical demonstration lectures by you guys.
This is very good...thank you

BUILD THAT WALL BIG BEAUTIFUL WALL
We cant there will be too much shear stress in the neutral axis
Just Brilliant
sir can i use your videos and translte in my language.
because it usefull some of the students.
Extremely helpful, thanks
this is excellent
This video contains wrong information, ( from min 2 to 5 ) this kind of shear stress will not be generated in the beam , because there is no difference in the stress along the x axis of the beam section , the only shear stresses are longitudinal and vertical. Correct me if I'm wrong please.
So it is leverage in the height and width instead of the length of the object
Say hello agrain. Please come back. We awaiting you.
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?
it is sad that i discover this channel after graduated
That's simply amazing!!!
M a r v e l l o u s e x p l a n a t i o n
Thank you!
Is this transverse shear stress or normal shear stress?
hello sir can you discuss about cantilever structure please?
the model is confusing. shear force depends on load placement. this model was all over the place without any clear indications of what axial load affected what shear part of the model.
a simulation with stress indication would go a lot further in this explanation than wooden blocks .
DarkShadowsX5 read the description
They didn't have computers capable of graphical stress simulations in 1976
I always cut thru the thick part when installing plumbing because thicker is stronger.
