How to Draw: SFD & BMD
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!

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!!
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
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.
This video just saved my life; awesome explanation of how to do the BM diagram
This problem is correct guys I checked with BMD calculator it gives the same answer. This video is awesome ....thank you so much :-).
i admit you have a sense of humor but be grateful for him for spending his time to teach.
brilliant video !!!! one of the best online to help out on SFD and BMD ! thankyoooooou
Thank you, summed up all my learning in one video
Dont know why my teachers make things difficult as much as they can. Thanks for this method, very good video.
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!
the video is pretty straight forward. Thank you sir, this should help me on my quiz later :)
This video was so helpful...Thank you for your time!
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 , you helped most of us a lot.
thank you for this videos. helps much my final subject for solid mechanic
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..
This is a great explanation, thank you.
U saved a 20 mark in my exam. Nice and clear explanation. Thank u
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.
You are a very good teacher sir. Thank you. It helped a lot.
thanks it is the only tutorial on KZread that i can understand
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
i love your videos thank you very much for this great tutorial 👍
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
Thank you! It indeed helps.
I am from Bangladesh. This video is a grat and make me a free.thanks for your good advice ☺️☺️☺️
Sir :) he deserves the respect.
Man last min study for my finalmis worth from watching this video. Thanks btw
why the curved is drawn below the axis i mean why is the bending moment negative??
Excellently explained video. Thanks a lot!
You are one of the best pro. Thanks a lot
OH!! Thank you so much that helped loooaaaddss !!
This is a great review. Thank you
Thank you! Please keep up the good work :)
Great video sir you have made me understand this topic with easy. cheers !
thank you so much for this video it was so helpful.
you might be saying okay a thousand times , but this is best video out there !

@@elacademy100 is there something wrong?? 17.5*2=55???
great explanation, thank you !
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
what if point B is abit longer in the beam ? like 1m further to the left, but the forces remain ?
wow ... i wish you were my teacher in uni ... very helpful
very clear and helpfull. thanks a lot!
What a good explanation I like it. Thank you
Did you use the convention with sagging moment as positive and hogging moment as negative ?
thank you sir.Very helpful video...............i like the way u use the word OK.......
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?
Great vid. Helped a lot. Cheers sir
Sounds like he is from Malaysia. Good video. Thank you.
He explained it fantastically
thank you very , now i have a better understanding about sad and bmd
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!
Thank you Mr. Asain man!!!!!
very very good video, this is the easiest way to learn bmd n sfd
This is helpful. Thank you :)
damn i only watch this once and already understand. finally an accent that i could understand and focus
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.
what if we see that thing from point B. is the diagram will be reverse?
This teach me a lot from what i’m not understand before. Thank you so much!! 😭🤍
Awesome Explanation!
For BMD,why is the 90kN curve outwards and not inwards?
it is very good and very helpful thank you man.
Nice, good vedio I almost learn SFD and BMD.
Thanks. Did you draw the bmd under the axis because the tension is acting at the bottom?

you are the best explaining ....thank uuuuuu
why did u draw 90kN/m on negative side in BMD
Great video Thanks mehn!!
Sir can you tell me how you get -17.5kn in sfd ? That part confusing me
really helpful!! thank u very much !! :)
WOWWW! I CAN'T THANK YOU ENOUGH!!!!

For the Bending Moment Diagram from 0m to 3m shouldn't the curve be increasing?
@hdot2613

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.
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
thank u best and kinda eaziest way !!☺
has anyone counted how many times he said OK

thank sir really very esaily find out sfd and bmd
Thank you for your valuable information
It Helps me alot... Thnk u😊
why have you drawn the bmd below the axis ?
Very nice video. helped me alot
brilliant, thank u.
Cool video Thanks for sharing.
