Shear in Beams Model

[@jamesramirez959]

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.

[@bernardoroux4500]

unfortunately it's like you say..

[@blakeb4583]

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.

[@robertmihalinac]

Agree, I am from Croatia, same here

[@adityakumarroyal7138]

Exactly brother even teacher himself got muddled up that's why unable to taught us what does it actually means and how it works

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!

[@alessandromorelli5866]

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

[@dhavalmysore]

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.

[@kingdomman1078]

I sincerely appreciate the effort dedicated to make videos like this. You help students much more than you think.

[@markspc1]

Best explanation of shear flow stresses in a beam that I have ever seen ! Thank you.

[@Victor-in1bs]

I miss having physical models in class. This is so much more intuitive!

[@eranlevin2260]

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.

[@ebaahaider908]

I have never seen anyone explaining the ideas this simple and easy I hope you make more videos and help us understand more.

[@serjerzemin]

I appreciate it very much Mr. Professor. This is the most elaborate explanation I have ever seen on KZbin. Thank you for your great efforts.

[@rogeramjet100]

Absolutely incredible explanation of something that has always bugged me for years.

[@kulkarniacademyofmechanica768]

The best that I found on KZbin till date. Thank u sir

[@biffsaxon3808]

I wish I could have had this explanation as a student. Incredible!

[@MeniscoManeiro]

If this videos were made more often, this channel would BLOW UP

[@andrewbismire6538]

Best shear flow explanation I've ever heard

[@rajumeena7932]

Everything is crystal clear now... Thank you engineering models 👍

[@mikeearls126]

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.

[@manishaprajapati8655]

Amazing ....one of the bestest explantion on ub tube about shear stresses.in beam. 👌👌

[@aniketghoman8412]

Thank you for such an outstanding explanation on shear distribution. It makes my life much easier now 🙌🏻 !

[@rahulnegi8041]

Jeez it can't get more clear than this. Thanks a ton mate for your efforts. 😘😘

[@CarlTelama]

Fantastic work. Will be sure to show this to any interested classmates

[@bruce-le-smith]

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.

[@benjaminlavigne2272]

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.

[@cranteri]

Looking forward for any updates and growth of this amazing channel. Really helps a lot with the understanding of engineering!!!

[@벵굴]

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.

[@bryzeng]

I could feel my brain shear under the stresses of watching this video.

[@eminashindahouse]

Now i really understand as to why bending moment is maximum at zero shear. Thanks for this video

wow, thanks for your sharing . clear ,very clear.civil civil engineering.

[@karanpatel-qf3ub]

You are right! In simple term: 2 different forces in different plan and in different directions of element cause shear force

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?

[@boustanisami7513]

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 ?

Nothing is more than this to depict.Its phenominal.. The long term dilemma is ended by this video.no professor can explain this..

[@tunglai1832]

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.

[@EddieVBlueIsland]

Nicely shown that S = dM/dx Shear stress is the differential of moment

[@liuzhihao3239]

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?

[@sanoopsiby8296]

This is very good...thank you

[@christiangeiselmann]

I did not understand what load is on the beam, in what direction, where, to start with.

[@massimookissed1023]

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.

[@benjaminlavigne2272]

P= - 412(down) @ A start with, watching carefully.

[@strikeforcek9149]

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.

[@pick3618]

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?

[@dard1515]

So it is leverage in the height and width instead of the length of the object

[@khudrghalii560]

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.

[@def6420]

BUILD THAT WALL BIG BEAUTIFUL WALL

[@JoseGarcia-ti6ni]

We cant there will be too much shear stress in the neutral axis

[@khizarkhateeb3325]

Is this transverse shear stress or normal shear stress?

[@darkshadowsx5949]

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 .
