Вставка
- Опубліковано 20 вер 2024
- Sheer force diagram (SFD) and bending moment diagram (BMD) are the most important first step toward design calculations of structural or machine elements. This video will demonstrate the steps to measure SFD & BMD.
this video has literally taught me in 14 mins what my lecturers have tried to do for the past two years!
LOL
Lol yeah 😂😂

OK
The best shear and bending moment diagram video here on youtube, you teached me what my teacher can't do in 1 week, thank you so much!
Thank you for the tutorial!! This has helped me a lot for my finals. Of all the tutorials I've watched, yours was the most helpful and understandable :) God bless you!!
This lecture makes me feel good after looking and listening to it. May Almighty Allah bless the person that produce it. It makes the concept of bending moment and shear force very easy to understand.
i admit you have a sense of humor but be grateful for him for spending his time to teach.
To all you guys saying the BMD was wrong, it's not wrong. Different disciplines of engineering have different standards, in some specialisations they plot positive bending moments downwards as it models what the actual beam deflection would look like.
True, if you also look at it this way, the udl acts downward making it tension in the bottom and compression at the top, hence the sagging curve. Thus, the BMD shows correctly how the beam would bend based on all the loads acting. Just a method of thumb, if you ever forget how to draw the BMD (above or below the datum), then just look at the UDL and imagine how it would act in real life. If you aint got an UDL to look at then...um, im sure you'll be able to figure out that the world is upside down.

this was such good and clear explanation, been struggling with SFD and BMD for a while, this cleared it all up
Thank you somuch, I feel so confident now. Al these years I have freaked out about this concept and never actually got to learn it since I was from the COVID batch and always kept puttingit away cause it seemed so difficult for some reason but this video explained it so easily. Thank you so much!
Dont know why my teachers make things difficult as much as they can.
Thanks for this method, very good video.
I am from Bangladesh. This video is a grat and make me a free.thanks for your good advice ☺️☺️☺️
he just draw the BMD diagram and not mentioned as positive or negative Bending moment. So don't get confuse on this it is very clear and a nice one for learners.what he done was exactly correct.
Man last min study for my finalmis worth from watching this video. Thanks btw
This video just saved my life; awesome explanation of how to do the BM diagram
thanks it is the only tutorial on UA-cam that i can understand
English is not even my first language, and I thought that I had problems to understand the british accent, but this guy... man, it was hard. But apart from that, it was very helpful.
This problem is correct guys I checked with BMD calculator it gives the same answer. This video is awesome ....thank you so much :-).
The note at the start of the video stated that the BMD will be flipped - so + Moment is shown down (-y axis). This is often done to better visualize the deflection and where the tension reinforcing steel should be placed. + Moment has compression on the top surface and tension on the bottom. So if you are supposed to plot the BMD with +Moment on the + y axis, just flip the image vertically. The rest of the procedure is still valid
Hi,I'm from Bangladesh, pursuing my btech in India..
Your video helped me a lot during my self -study period...
Thank you so much...keep the good work up..
Oookey... I thought i was going to learn about the SFD and BMD ok!
But i learned how great the word OK is, ok! So the time was'nt totally wasted, ok!
How do you know if the curve for the bending moment diagram is convex or concave?
Thanks this helped me understand BMD a lot better.
Also people should depending on your course you might put bending moment in the opposite direction but I'm doing Civil Engineering and that's how we do it.
Thank you, summed up all my learning in one video
thank you very much !!!!! helped wit my exam
Thanks Darroll! Glad you find it helpful.
@@elacademy100 is there something wrong?? 17.5*2=55???
U saved a 20 mark in my exam. Nice and clear explanation. Thank u
You are one of the best pro. Thanks a lot
Sounds like he is from Malaysia. Good video. Thank you.
brilliant video !!!! one of the best online to help out on SFD and BMD ! thankyoooooou
you might be saying okay a thousand times , but this is best video out there !
He explained it fantastically
You are a very good teacher sir. Thank you. It helped a lot.
Thank you , you helped most of us a lot.
This is a great explanation, thank you.
very very good video, this is the easiest way to learn bmd n sfd
the video is pretty straight forward. Thank you sir, this should help me on my quiz later :)
Excellently explained video. Thanks a lot!
Great video sir you have made me understand this topic with easy. cheers !
thank you for this videos. helps much my final subject for solid mechanic
Sir :)
he deserves the respect.
you are the best explaining ....thank uuuuuu
thank you sir.Very helpful video...............i like the way u use the word OK.......
why the curved is drawn below the axis i mean why is the bending moment negative??
This video was so helpful...Thank you for your time!
For the Bending Moment Diagram from 0m to 3m shouldn't the curve be increasing?
I think he's drawn the positive values for the BMD on a negative axis. If he plotted the points on a positive axis, he should get a convex increasing function from 0 to 3m ranging from 0 to 90kN/m.
thank you very , now i have a better understanding about sad and bmd
wow ...
i wish you were my teacher in uni ...
very helpful
This has more oks in 14 mins than laughtracks in friends
damn i only watch this once and already understand. finally an accent that i could understand and focus
I didn't notice how many times he says OK. I'm here to learn SFD and BMD and now I got it. Be +ve and think about his effort and also the BMD is not wrong
rudra rise that's the point...we are here to learn what he is teaching... Not about the same word he is speaking again and again...everyone has their different of teaching....
Those who are trilling this guy are piece of shit
Thanks. I could developed my SFD successfully by following your lecture. However I have one question though: is the shear force staying in upward position always being positive?
THANK YOU SIR!!! I UNDERSTAND YOU BETTER THAN MY INSTRUCTOR... :)
The BMD should be positive.. as the load is making the beam saggy hence the bending is occuring in a positive direction. Even further maximam BM occurs where SF=0 hence it cannot be -90KNm considering this case!
Immensely helpful video! Thanks man!
Thank you!
This teach me a lot from what i’m not understand before. Thank you so much!! 😭🤍
nice one concept is same but the way we solve is different i liked it. could you make some more videos on couple acting or fixed beams
Sir it is very use full to us thank you sir for providing this vedio
Nice, good vedio
I almost learn SFD and BMD.
Very helpful.. thank you and never mind the negative comments until your methods are correct :)
it depends.
usually, we take the shear force diagram as, above the x axis as POSITIVE and below, NEGATIVE.
In bending moment diagram, its vice versa. below is POSITIVE and above is NEGATIVE.
correct me if im wrong :)
One doubt...Last section in bending moment diagram...2nd area you have subtracted.from 1st area.....in last area you have drawn same area...please clarify
A shot of Tequila everytime he says OK! Great Explanation though! Thank You!
BMD diagram is correct. This is typical of BMD for structure since it shows the location of reinforcements required.
i love your videos thank you very much for this great tutorial 👍
What a good explanation I like it. Thank you
I thoughtn converting udl to point load we did 5*3*3/2..but when we were getting the total load we only did 5*3...Pls can you shed more light....because am confused atb this point.
Thank you for your valuable information
if for instance I had a beam which was 4.9m and had a 1.4KN downward force on the far left point and then 1.5m to the right had a 1.8KN downward force and then 1.6m to the right had point A and then 1.8m to right had point B (B is a fixed point) does it matter where the points are to calculate RA and RB
sir I have doubt regarding the calculation of bending moment of simply supported beams with uniformly distributed load why in some problems BM is calculated as (W×L^2)/8
sir can u pls help me with this doubt I really need the answer
WOWWW! I CAN'T THANK YOU ENOUGH!!!!
has anyone counted how many times he said OK
It's 56 times.
eLA Taylor's Thank you OKAY!!!!!????
eLA Taylor's it was helpful.....jazakallah
+Sensationalism uhh ugggghhh can u tell the formula used at 32nd ok? okay?
d
why did u draw 90kN/m on negative side in BMD
the video was awesome easy to understand
it is very good and very helpful thank you man.
i just don't get it when he says 27.5 x 2 equal to 55knm... reply asap
what if point B is abit longer in the beam ? like 1m further to the left, but the forces remain ?
Thank you Mr. Asain man!!!!!
unit size is 140kg ( variable load apply on base of the unit) but how to calculate bmd & sfd diagram
Great vid. Helped a lot. Cheers sir
Sir can you tell me how you get -17.5kn in sfd ? That part confusing me
very clear and helpfull. thanks a lot!
Did you use the convention with sagging moment as positive and hogging moment as negative ?
Has anyone noticed that the value for RA and RB are wrong RA+ Rb = 65, RA= 35.36 RB= 29.64
thank you so much for this video it was so helpful.
Thank you! It indeed helps.
OH!! Thank you so much that helped loooaaaddss !!
For BMD,why is the 90kN curve outwards and not inwards?
Very nice video. helped me alot
Thank you so much , it's help a lot...
really a great help sir thank you very much
Awesome Explanation!
Youre very welcome dor attention my humble teacher.
Thank you from Korea🙏🏼
what if we see that thing from point B. is the diagram will be reverse?
Thank you so much for this video for me man
Thanks Chandara!
It Helps me alot... Thnk u😊
clockwise -ve anticlockwise +ve for moments?
thank sir really very esaily find out sfd and bmd
here in BMD yo have mentioned tat 17.5*2=55... hw can yo explain briefly please
The bending moment diagram was wrong. I'll write the detail later.RRC Wiseguys
+RRCWiseguys please can you solve the bmd for the question

The Parabola of BMD should be opposite that he did.
its not wrong, in europe (including UK which is where i live) we do what he did in the video, however in america, it is the opposite way round in the vertical sense.
Shear force is defined as a force which acts parallel to surface. Then why is it always represented perpendicular to beam in SFD?
no shear force is the force that acts perpendicular to the cross section of the beam
