You are the legend of structural analysis. If I ever make it big and I will one day, I am gonna make a huge donation to your channel. 🤞
You did that better than my professor
You're a champ. Your videos are very easy follow, making complex topics a breeze. When I have a bad lecturer (hard to understand, or just has a voice that puts you to sleep!) I come and watch your stuff! GREAT!
Hey man, just wanted to thank you for this video along with all your videos. They have really helped clear up my muddled understanding of my structures classes that I barely attend because of how early it is/how difficult it is to understand. But you explain this stuff in a way that makes it so simple, keep doing what you do, you are greatly appreciate bro.
Kassra Rafiee Thank you for your comment. It is very encouraging and humbling to know that the videos are helpful outside of my own university. Let me know when you graduate!
i am a student of mechanical engineering. i also had to study mechanics of material and the course became easy because of the videos. thnx for explaining the stuff in easy ways.
this was 10 years ago? the quality is soo good,and it helps me even to this day!
Please turn me into a Big Mac.
you don’t know how much this means to me, Thank you so much sir 😊
exceptionally explained.........You deserve over million subscribers
Great job @structurefree.
your lessons are awesome and real helpful.I just love the way you explain the things.
Very nice example. Good video quality and excellent audio.
very interesting way to make one understand a complicated problem. thank you very much for this video
wish I could just like this a million times!
+Ammar Abbasi ha, ha, ha! thanks. i'll try to make a million videos so that you can reach your goal of liking them a million times.
+structurefree you must have a partner that is really proud of you! - take notice young minds that +structurefree is the luckiest guy around here making amazing videos
hello, can i ask a question. why the moment A is negative (-54kn.m) in the moment diagram eventhough it is positive actually like calculation in the reaction, which is +54kn.m.
Very Simple & Straight forward subscribed for future reference.
Really helpful!! No need of asking anything!! thumbs up.... :)
Amen to you @structurefree for not using functions, it helps alot
Quite a lesson... :).. keep clearing doubts sir
Man i love your video's, laid back but extremely clear with well made drawings. My teacher never explained this method but its so mutch easier to use in allot of cases. Where do i donate allot of love and a a little moneys? :P
sorry i just dont get on why 18 kN/m be at the middle between A and B?
Thanks sir very good teaching method..... effective way.👌👌
So sorry. I am very confused as to why the 54 on your moment diagram is negative even though your sign convention says anticlockwise is positive.
Thank you :)
The shear and moment diagrams use an internal positive sign convention. Equilibrium equations use a global reference frame where counter clockwise is positive.
Anand Singh The anticlockwise moment is by the fixed end. As in that's how the support... in this case fixed...restrains the clockwise moment of the beam. The BMD is drawn for the beam. Hence accordingly its shown negative as it is clockwise.
Thank you for your explanation it really helped me.
Sir, i just want to clarify, -MA+18-(6x6)=0, answer is -18kN-m...it was being thought in school that clockwise is positive and counterclockwise is negative or if vice versa the answer is still the same..but there the answer is -54kN-m..i'm sorry, that is so confusing..
this video showed up 2hours before my exam thank goodness
hey
are have any explanation for matrix method (stiffness method )
thank you so much. last question. if deflection at c is distance between tan a to c, then what is slope?
Why does the moment graph below the x axis and not on top of the x axis
According to the sign convention that I use for internal loading, moments that cause compression at the bottom of the beam cross-section are considered negative internal bending moments.
Can you please tell me how did you know that those moment will be concave down ? thank you ..
Is it completely right cause while finding x bar won't we need to divide Sigma AiXi by Sigma Ai?
Thank you very much sir. I learned a lot from you.
Thank you so so much! I love you! I think I just turned straight. thanks again!!~
i am not sure when choosing the centroid , which side to start from, you were mentioning fat ad skinny side , I am still confused about it lol
Think about it this way. If you were to place the triangle on say, a ruler, and wanted it to be perfectly balanced and level, where would you place the ruler? It would be closer to the fat side to accomodate for all the extra fat. Same principle applies. The centroid (note "center") of the triangle is 1/3 from the fat side to accomdate the extra fat, or 2/3 from the skinny side because its skinny.
Your videos are really helpful and thank you for that also that jokes are really keeping me awake :)
STRUCTURE FREEEEEEEEEEEEEEEEEE ! Timeless classics
If there wasn't an applied load at point C, how would the deflection diagram look?
Excellent!! Well done!!
hey. what books or reference are you using?
This helped me a lot, thanks champ!!
how to get the maximum deflection using this method ?
Why does the unit of θ B kn.m2 ? shouldn't it be in radians, since it is an angle?
marian joyce macadine if we substituted values and units for E and I, the units would come out to radians. i hope that helps.
bu sporu yapiyosun babacım helalll
how did u actually draw the moment diagram
It may help to practice drawing some moment diagrams before jumping to the moment area method. Check out my statics or mechanics of materials playlists.
very helpful lecture
You are AWESOME!!
Its really clear now. Thanks!!!
Hey, thanks so much for these videos. You should be like another Salman Khan or collab with him!
Are you by any chance a professor? Either way you exceed the teaching skills and humor of our prof, a dean on our college 😁
yet again you saved my ass
Thank you
sorry.. how did u get 36 kN/m ?
Thanks alot you better than my doctors😂
could u do plastic analysis pleaseee
perfectly taught
how is it -675, when I got -729 in my calculator?
You had divided the moment by EI and said that the curvature now is the same as the moment BUT I think this is not true because the moment diagram is a function and dividing it by some value will cause changes to the slopes .... changing tthe shape of the diagram itself ! Only subtraction and addition are allowed with a transition of the curve but keeping the same shape
Hello please can you make a pdf of the content of this video ... it would be helpful..
Thanks by the way
i think it was good class
very helpful.
You just saved me from bombing my test tomorrow because of a shitty professor, Thanks!
There is a major problem in finding the angle at B, he didn't include the area of the rectangle under the curve, only the triangle!
He calculated the area of the trapezoid, which is the combination of the rectangle and triangle
magic breaked ☺
Thank you so much!
My professor had a beam with “4i” written under one section of the beam and “i” written under the other half of that beam; would that be an example of when the curvature diagram would not bead straight forward because EI changes??
thanks a lot
m^3 not m^2 like in virtual method????
thank you too much,so much,very much...
very helpful thanks chief
thank you, you champ!
M8 U R GOD !
BIG MAC YO
Guys can anyone suggest to me someone who explains this topic properly. I'm not understanding anything
Practice?!?! We talkin' about practice? Not a game...practice?!
got a min 675 to figure out how
hey man, im learning civil engineering in israel, and im trying to find a video on a certain topic that i can only translate from hebrew as "loading points method" where you load a unit force on certain points after breaking up the structure into sub-structures. its an aditional (other than the muller method) method to finding influence line. hope you can help! your videos are awesome!
shit got real now :\
im a medium fry
thank you
