I had always had trouble with understand what bending moment really meant. Your diagram showed the BM as something arising from the internal forces along the length of the beam; this is honestly the first time in years that I have really understood it. I've read so many lengthy explanations in books and on the internet but not one gave a succinct and visually apt explanation as yours. Thanks a million and keep up the good work!
I was fascinated by how you explained car transmissions, so I subscribed and looked at your page. I was so glad you also cover structural analysis because I'm a graduating Civil Engineering student and it would be good to hear about what I'm studying and maybe I can learn more because of how you explained them!
😂 much thanks for making this so clear, I watched the entire thing, I feel mentally violated. Special thanks to the robo-voice for your amazing timing and skilled broadcaster expressions😂
There are literally millions of people out there with the professionalism to speak the language of science without adding "human shit". However, of the robot voices this one is the least aggravating.
Sfd and bmd is used to calculate the Shear stress and Bending Moment. Sfd and Bmd will give us the distribution of Shear Force and Bending Moment produced in the Beam. Once the Shear force is know, Shear stress can be calculated using Stress = F/A, and if the bending moment is known, Bending stress can be calculated from the Flexural Equation. While designing a structural member Sfd and Bmd helps us to know the Shear stress and Bending stress induced in the beam. These values can be compared with the safe bending stress and shear stress value and we can determine whether the design is safe or not. Now, coming to your question....If the values of bending stress and shear stress induced in the beam is more than the designed shear stress and bending stress, then beam is likely to undergo failure. Note that Bending Stress acts perpendicular to the c/s of the beam and Shear stress acts parallel to the c/s of the beam.
Is shear force and bending moment diagram is unique for a given beam? If yes, why does different text books use different sign convention and diagrams?
3:57 -> section "C-D" you write moment equation [F1.x + F2.(x-L1) + F3(x-L2)] but I mean it is wrong. Because instead F3(x-L2) should be F3.[x-(L1-L2)].
+Thomas Thor Yes you're right :-D. Initially I wanted to write F3[x-(L2+L1)]. I guess I have the same problem as the author because my mind thinking about one thing and my hands writing other thing :-) I appreciate your suggestion.
The bending moment is the integral of the shear force with respect to the distance, x. So as shown by the video when the shear force is constant the moment is linear , when the shear force is linear the moment was quadratic, and so on. This means that the shear force is the derivative of the moment, therefore, when the shear force (the derivative) is at zero, the moment must have reach either a local minimum or maximum.
May have good info but the rise in computerised voice over makes so many switch off, which is what I will do once posted. Imagine if this pervaded into the film or music industry? Stop it at once!!!

shreetron Who the hell taught you
Yaa
@@pabloruiz8551 A so called professeur.
The understanding of shear force and bending moment is now easy for me. Thank u respected sir 😀😀🇨🇮🇨🇮🇨🇮🇨🇮🇨🇮😃😃😃😃😃
It's 2023 and by far the most easily explained concept of beams on youtube till now...

This video is very explanatory on shear force and bending momentum’s . The formulas were explained very thoroughly and shown with well made diagrams.
Super expln if only I had prof by your sfd BMD lecture. Marvelous god bless your good self o hit the bell subscrined
Very informative videos with engineering detailed presentations using animations. Great work.
😂 much thanks for making this so clear, I watched the entire thing, I feel mentally violated. Special thanks to the robo-voice for your amazing timing and skilled broadcaster expressions😂
It would really help your videos to have a real person talking..
No ! people ruin the pure science by adding human shit in them.

MrDabbio92 - Also to fix the spelling.
Thank you very much. I finally understood how bending moments are developed in sections!
omg now i finally understand what exactly shear force is, thank you very much :)
good one
i am really starting to love your channel !! Please keep up the great work !
very clear, thank you so much !
Sir please give more videos of civil engineering its very very helpful for us sir please 🙏
It was an awesome learning experience...:)
It's help a lot... thank you...
plz do upload more videos.... :)
Great!! Which program do you use for animation?
good...keep it up...
very good ..........
at 3:53 bending moment due to F3 should F3 X (x-(L1+L2))
yes ! I have been rolling down to look for this comment and make sure abt my doubts
which software is used for this illustration?
outstanding sir
Prepare one such complete video for industrial shed if possible
Please Upload mire vedios on Civil Engineering .Thanx alot fr this :)
THANK YOU! CAN YOU TELL ME WHAT PROGRAM YOU USED TO ANIMATE IT?
good ...can u explain y we need the sfd and bmd diagram?? which force causes failure of the beam

Amezing
Mistake at 4:00 in getting the bending moment of the last part of the contilever
yes it would be F3(x-{L1+L2}) ... Am i right ?
Is shear force and bending moment diagram is unique for a given beam? If yes, why does different text books use different sign convention and diagrams?
Sign convention doesn't matter, anyway final answer will be the same.
quite good
what an explanation
Thanks!
Please make a video about carborater
which program is used for animation?
3:57 -> section "C-D" you write moment equation [F1.x + F2.(x-L1) + F3(x-L2)] but I mean it is wrong. Because instead F3(x-L2) should be F3.[x-(L1-L2)].
+Peter Kačmarik it would actually be F3[x-(L2+L1)] as it's the distance from the axial rotation point that determines the moment arm.
+Thomas Thor Yes you're right :-D. Initially I wanted to write F3[x-(L2+L1)]. I guess I have the same problem as the author because my mind thinking about one thing and my hands writing other thing :-) I appreciate your suggestion.
Haha no worries. I thought you might have meant that. It was a cumbersome way to approach the question by the author, in my opinion. :D
Perfect
Thanks man
Why Bending moment is maximum at a point where shear force is zero in the above diagram?
The bending moment is the integral of the shear force with respect to the distance, x. So as shown by the video when the shear force is constant the moment is linear , when the shear force is linear the moment was quadratic, and so on. This means that the shear force is the derivative of the moment, therefore, when the shear force (the derivative) is at zero, the moment must have reach either a local minimum or maximum.
Thank you...
In my uni, the bending moment signs in the tensile side just opposite with your bending moment diagram.
I have dougt in my life .. how is form bending movement and shear force....
can we have a video on moment of inertia, area moment of inertia?
thannks
What is the difference between Mbend and Mforce ???
why the bending moment in case of cantilever is negative?
beacuse it should be oppsite of what the load is acting which is positive.
thanks
written text background should be transparent. plz keep in mind.
Bending moment of the beams
3:47 correct the x length
this channel is not learn engineering.. this is learn mechanical engineering 😅
I didnt know these forces are induced OMG My whole Engineering life s a lie
lenght is wrong when calculating bending moment
May have good info but the rise in computerised voice over makes so many switch off, which is what I will do once posted. Imagine if this pervaded into the film or music industry? Stop it at once!!!
Please use your own voice. It was easier to understand compared to this computerised voice which is a bit annoying. Thanks
Beam
Why does the narrator use broken English. Its sounds like a Native American autobot.
+Maxx McGerk It is a robot, text to voice program.
VirusKing
I'm not sure. I have come across one before but this seems like a foreigner.
Just kidding. Come on. That is why I said Autobot.
wyhy the fucc , half of people crazy about accent on this planet??
Why this autobot voice???
Please translate to arbic language
