This model makes it easy to understand how shear stresses develop in beams. It was inspired by a photo in the 1976 textbook, Mechanics of Materials by E.P. Popov.

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.

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.

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 5 жыл бұрын

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.

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?

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.

@strikeforcek9149 5 жыл бұрын

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.

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.

@darkshadowsx5949 5 жыл бұрын

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 .

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.
