Understanding and Analysing Trusses
Вставка
- Опубліковано 16 тра 2024
- In this video we'll take a detailed look at trusses. Trusses are structures made of up slender members, connected at joints which can be approximated to pinned connections.
It is typically assumed that loads are applied to the joints of the truss, not directly to the members. Because of this, the members only carry axial forces - they do not carry bending moments. The internal force in each member is constant, and a member can be either in tension or in compression.
It is important for engineers to be able to determine the axial force in the members of a truss, so that they can be designed appropriately. In this video I cover the two main methods for doing this, which are the Method of Joints and the Method of Sections.
The Method of Joints involves applying the equilibrium equations to solve the internal forces acting on every joint within the truss.
The Method of Sections involves creating an imaginary cut through the members of interest, and applying the equilibrium equations to the external and internal forces.

This is why the internet is the biggest source of free education in history.
Noble prize 🤣🤣
@@alwynwatson6119 it’s also, way too often, the actual single useful one
I wouldn't go that far
It’s both a blessing and a curse.
It's really amazing that I'm paying thousands for a shit powerpoint presentation at uni, only to learn from this guy's free youtube videos of much higher quality.

Facts
The Internet is revolutionizing learning. Universities just haven't realized that yet.
@@SomeTechGuy666 Universities today are for political/gender/racial studies and the exclusion of (some) people based on their beliefs; quite the opposite of what I thought college was in the 70s. Back then, it was a general attitude of party and learn your speciality, and "screw the man." Today it appears to be "party and I'll get passed for not arguing with the Professor" and "Screw anybody with different beliefs than my own, identified, special group."
@@ZenZaBill "party and I'll get passed for not arguing with the Professor" Not in STEM. Maybe in liberal arts. In STEM you either have the right answer or you don't.
The animations are unreal. This is the sort of content that helps aspiring engineers learn effectively!
does any one knows what software is used to create those animations ?
@@edgarcarrillovazquez8576 floor pan 3d
Plz suggest me which software used
I am a structural engineer with a major aerospace company and I cannot tell how how well made these videos are. I am so impressed that I actually watch them every now and then Just to stay in touch with basics. Helps develop intuition. 😀 thanks efficient engineer.
Do excuse me, I'm like hella stupid when it comes to this kind of stuff, but as for the 20Kn number, is that just an example of force? and if you wanted the real number or amount of force, you would need to calculate the weight of all components? and or additions to the structure?
@RUSTY NEEDLES Yeah, usually for structures you calculate the dead load, which is the load of all the structural members, eg beams, columns, then you add the live load, which is the load of things like trains, cars, pedestrians. Then you add in wind and earthquake loads, and multiply all these loads by their respective factors.
After which you get the moments and shear forces from these loads, and use these moments to figure out the rebar required per slab/beam/column.
Hello.I need a mentor,am an engineering student
@justhangingaround804
Hi, I am studying aerospace engineering and its my last year. I would love an internship opportunity!
Wow an entire statics in 17min. Seriously if my teacher would have showed this video the first day of class and then given us problems after that it would have made that entire semester so much easier!
I showed it to my teacher and his pants are now wet'
I had the same thought, almost word for word, as you stated in your comment. I was halfway through my first statics class at BYU before I started being brave enough to ask "what is a moment?"
@@thepianist7084 have you had any physics class before that?
@@milanstevic8424 this is the damn response from my teacher whenever I ask him question rather than giving me the straight answer
@@thepianist7084
I'll tell you... but in just a moment!
Wtf how did i just found this guy now, he's the 3b1b for engineering. Keep it up mate. Insane quality!
So true
I wish I were surrounded with people who could explain and demonstrate engineering concepts like this. I have a deep fondness for well-explained engineering with a healthy dash of history added in.
It's rare to have the luck to be around or raised by such people, but at least we have presentations like this. If you like this stuff go for it.
🎉
How much work went into this! man I can't imagine what it took to make all the animations, the 3d bridge, the stress points simulation. Dude you must have some serious skills!
just amazing, your work deserve millions subscriber.
Who are you?
You have come like a blessing to us engineers. All my ♥️
Bhai kn semester m ho?
@Nawneet Kumar if what you are saying is true, then you really need help. You are not an engineer. This is basic engineering, not rocket science. This is literally basic trigonometry
This is by far the most trussworthy video I have seen on UA-cam. What you do is absolutely priceless. Thank you sincerely.
Simple, concise and better than anything uni could give me. Cheers mate you’re a legend ❤️
Funny, my uni recommended this video for revision purposes
@@julzcrafter8383 good for you,i didnt have such teachers in my college
Really? What university are you talking about
@@_qwe_fk_1700 have basic knowledge before trying to be oversmart,nkt every college teach str in its first sem
UHHH HELICAL WHY U HERE. ROCKET LEAGUE BOI
The best channel on UA-cam to understand any concept of Mechanical Engineering.
This video is what civil engineers design not mechanical.
its Civil/structural you thic clot.
@@oot007 It is part of Statics which is in ME.
@@zunaidhassan9662 This video is focused on the use of trusses in structures which only Civil/Structural Engineers are qualified to design. ME are not qualified to design bridges etc.
@@oot007 Did OP talk about designing bridges before he edited his comment?
What I don't only understand on this video is that...
Why does this have 200 dislikes even though this had the best representation and explanation of trusses? You deserve more recognition, sir!
Maybe jealous Teachers clicked on it.
@@javierlinarez1747 lol true
All those teachers reading the positive comments got real jealous
What you don't understand is that under all of the truss bridges live trolls.... :)
@@falloutfan2502 truss trolls
Censorship forbids dislike. There was none
Thank you for this video. You just explained to me in 20 minutes what my professor has not been able to in 2 months. It's so simple. I didn't realize it. I will sleep better tonight actually understanding the hw I just suffered through this evening. Wow, and to think, I hated my statics class. It's actually quite fascinating. I am so watching all of your videos for next semester. Dynamics and strength of materials just became a lot less dreadful!! You're awesome. If I could, I would 'like' this video 1,000 times.
PURE GOLD! Thank you for taking me 15-20 years back in time, explaining “things I should know” in such an easy way. 👍
Your channel is exceptional. I wish I could go back in time to when I got my BSME and have these videos as introductions to all my classes. The quality, clarity, accuracy, and delivery are legitimately better than what you would often get in university courses back when I attended. Thank you for all you do. You’ve probably helped more students understand these concepts than you could imagine.
I am a graduate of Civil Engg in 1979 and my professors were still primitive on the way of teaching. The calculators have been invented introduced late during my studies. My professors did not explained to us in detail about the design of trusses. It was up to us to dig out . Your channel is very much helpful in understanding the structural analysis of truss. This is a huge help for Engg students and also those who graduated in a less college or university of less standard in teaching . Your channel is amazing.
The regret i have for not finding you sooner you are better than any professor I’ve ever had, literally an angel sent from above to help us students learn.
The bridge building at 3:39 was so cool! We need people that can give us an idea of a concept in an effective matter, and you are that person!
although i passed those classes a long time ago and I understand all the concepts perfectly it is so nice to see them in action through such pretty animations . You have done an amazing job sir
I remember how I suffered back in college with these subject, so bad I didn't watched this a couple of years ago.
Very easy to understand, I smashed the like button
I went back to my university years, very well told and quite simple presentation despite the obvious hard work behind it. anyone with basic physics knowledge would easily understand the principles. awesome channel, hope to see many more. thanks for the awesome contents.
I'm in my 4th Semester of Civil Engineering, have calculated 100 trusses, but this video is so much better than anything I have ever seen at uni! Please keep them coming!!
We need more channels and videos like this. Thank you very much for taking the time and making such videos. I wish I had such resources when I was in college. I want more of such videos from your side but understand that it takes time to do research, do all graphics work and put together a video, and rushing will only lead to a decrease in quality. I want your videos to reach out to all the students.
One of the best channel on UA-cam for efficient engineers. Thanks for making such well explained and clear video
I've never really had an interest in engineering , but with the way you present things, you are beginning to change that.
It is very sad that there are so many videos in UA-cam which are gaining wasteful views. But seriously this channel and its videos must be have views and subscribers in millions. Really very valuable for all engineers. Thank you sir from bottom of my heart your videos always clear my concepts. Respect your hardwork and efforts. Love from engineer. 🖤
This channel could replace my engineering degree. Seriously, these videos should be shown to all engineering students.
How did I not come across this channel before? The quality of content is top-notch. You deserve to have a million subscribers atleast.
Been 35 years since I learned this. Thanks for a great explanation. Brought back great memories!
Channels like this help me (a city planner) make informed decisions and make the lives of my contacts in other fields a bit easier without having to go back to uni or buy access to this info in other formats, thank you!
These videos are so helpful. I’m currently reviewing for my Statics class’ final exam! These videos are very engaging! Can’t wait for more.
Simply beautiful! The visuals are such an aid to understanding. Well done and please keep making videos!
Students of today's generation are lucky to have this kind of demonstration and lecture. The Efficient Engineeer is worthy of praise for this content. Bravo.
Very good explanation. I'm a Civil Engineer and I am glad the way you resumed and gave a good overview of the truss analysis in less than 18 minutes. Again, well explanation.
As a mechanical engineer myself I have to say your channel is literally treasure!
Keep going my friend.
As a proposal ,it would be nice if you do some finite element analysis videos!
Exactly i do wish the same!
Do excuse me, I'm like hella stupid when it comes to this kind of stuff, but as for the 20Kn number, is that just an example of force? and if you wanted the real number or amount of force, you would need to calculate the weight of all components? and or additions to the structure?
@@rustyneedles3743 this is a basic understanding and explanation of forces. weight and mass are different, weight being the force acting on an object with gravity, while mass being the amount of matter in an object.
In this example, take it as the force acting on the object is xxKN, with gravity and mass of the beam being accounted for, as Weight (kn)= mass(kg) X gravity (m/s2).
of course in reality there are alot of forces acting on the object, the type of material used for the beams, the type of bolt used etc.
But the law of equilibrium and the law of moments about a point does not change.
Man, you just made structural analysis into a fun informational cartoon. I love it. love the colors i love the pace. Good going.
Top rated!!!
I tell you even 2 of my Engineering Statics Lecturers in the University combined, can't beat this.
What my Lecturer spent a month lecturing on (which obviously I didn't understand a thing), was done in just 17 minutes 40m seconds.
This is AMAZING!!
You deserve an AWARD.
Thanks man.
Amazing quality and I really recommend this to anyone as an introduction to understand what's going on in engineering courses. And also, for anybody that had already studied and want to remember, like me.
this channel is truly a hidden gem
❤❤❤
An engineer need to be efficient and your channel makes sure the same.Thank you for creating such a wonderful channel and helping us understand the concepts more practically and in depth.Keep it up guys😊All the best!
I just can't express myself to thanking this channel.
Definitely there is no alternative easier way to understand this type of tough topic.
Just amazing work!
Thanks a million from the deep of my heart ♥️♥️♥️
Really remarkable, thanks so much.
Somehow you have managed to simplify what a year at uni could not. Don’t know whether to be amazed or disappointed.
Thank you😊
Your videos are outstanding. Easily one of the best channels to learn engineering concepts.
Keep it up!
Not sure why I had to take Statics as an EE major, but I ended up enjoying the class. The professor was one of the most helpful teachers I ever had. He took the time after class to help people understand, which for some reason ticked of the chair of the Civil Engineering department. He was let go literally because too many people passed his class. Great video!
Not many professors like that...Backstabbed out for going the extra mile...
All the appreciation in the world is not enough for the quality of this video. The animations really made it easy to understand the concepts.
That trig recap...one of the most beautiful and intuitive demonstrations I've ever seen 🥲
Lightweight is good and what did I use it for it’s a lawnmower ua-cam.com/users/postUgkxTPN04aT-Qdjr_KS3ql7ng8wnU3wwsCqk also recommend Yes it is lightweight so hence not as robust as our old one. But if you take care it does the job really well.
This takes me back to all those hours I spent playing Bridge Builder and the Pontifex series. Good times!
Indeed, although bridge builder does not give numbers, I use it to (g)estimate if my a-symmetrical shed roof could be used to hoist my motor cycle.

This is amazing. I have a horrible engineering teacher that taught us essentially nothing and now you are here to bring my hopes back that I will pass
Studying for the FE Mechanical exam after 14 years out of school. This video effectively and efficiently (ha!) got me up to speed on the two solution methods for simple trusses. Thank you for the free lesson!
Buddy Thank you ! Visualisation makes the concepts more effective to understand , please keep us surprising. Stay safe and take care ! Also the one reading the comment.
These are the best structural videos I've seen so far on UA-cam. Thanks for the great work and sharing these. If possible please do some on thin walled shell structures as well. (Aircraft wings for example)
I just started work as a structural engineer, and I enjoy watching your videos. Great content
this is the 5th time that i always come back to watch your videos. They are by far the best out here!
efficient editing my friend, very thorough and consistent. you got a free sub here man! keep up the amazing work!
Absolutely amazing work. Your videos are perfect for understanding all these essential topics on engineering. I would greatly appreciate a video on yield line theory whenever possible. Keep up with the great work!
So glad I found your channel, I've never seen better explanations!
you have taken engineering to a new learning platform. With these video's learners increase their imagination levels. Thanks for your efforts 👍
This refreshes my memory. I learned this 40 years ago as a mechanical engineer.
I don't know why but it made me feel sensitive, respecting you !
Thank you so much, I have lot of struggled to understand this since my Engineering.
Your videos just plastered a solid path for my mechanical engineering exams in a few months
last year for my statics class I wasn't able to watch the lecture video for trusses, and the final exam was only about trusses. This video is the sole reason how I got to learn how trusses work and equip the knowledge to conquer the class!
Loved the animations with how the videos of this channel explain the concepts. Felt nostalgic of when we're taught Engineering mechanics in our 1st semester at IIT ISM.
Gr8 job guys. Really appreciate it.
Ankit, which truss design would be strongest if increasing force were being applied to the the center of the base?
Such an under-rated youtuber ...... Such content will make 3B1B run for his money

This is simply legendary, engineering concepts are not hard, only if you have a good teacher.
Thumbs up Man
7:00 Brilliant animation showing the relationship between sine and cosine.
oh dig this
s0 = 1.f; s1 = 0.f; // init
s0 -= w * s1; s1 += w * s0; // loop
where w = tau * freq/samplerate
Glad I watched this video. It helped me get over my "truss" issues 😏
Coherent and straight to the point. You are an excellent teacher, I thank you.
THIS CHANNEL IS BY FAR THE BEST ENGINEERING CHANNEL I'VE SEEN ON UA-cam! KEEP UP THE GOOD WORK!
Where the hell were you 10 years ago? I suffered for days trying to understand trusses when all I could have done was watch a video like this :(

This is one, if not the best, of the channels that you can really understand the concepts of what you are solving.
This channel is a treasure for engineers!

I had never known that the sine and cosine waves were made from the circle stuff
Most excellent!!! This very clear video gives me valuable context before I even crack a textbook, thus making learning more efficient, fun and more satisfying!!! The best way to learn is to first have a good idea of overall context, then fill in the blanks instead of the arduous and uncertain opposite method of creating context from heaps of minute details!!! Thanks!!!!
This video is amazing. I wish I saw this a year ago when I was taking statics. Perfect.
