haha Totally agree with you! this is by far the easiest way to comprehend moment of inertia. I also found this cool moment of inertia calculator skyciv.com/free-moment-of-inertia-calculator/ which makes my life easier.
I just spent about 2 hours scrawling through the internet and lecture notes trying to understand this, you clearly explained it within 10 minutes, thank you, really great teaching & video :)
Thanks a lot sir. While problem solving, I realised I forgot this calculations. Again I needed to search book. Instead watching your video was much better. You really make me remember the calculations and now I can happily apply to the numericals. You were really very precise and to the point. Thanks once again
I just got my exam back, and I wanted to say thank you. I got 30 out of 100 marks (that's not my grade lol, but the question was worth 30) because of you! so like 30/30 on the question weighted 30/100. Thank you so much :)
Great Video! I adapted the calculations to angle iron and was able to compute an answer. I later found an angle iron calculator on the web and confirmed my math. If my prof for the one mechanical course I took had been this good, I might not have become an electrical engineer or at least would have double majored in electrical and mechanical.
Again, great video. I tried to race you in solving this problem and I wound up getting the final answer but I freaked out because I thought your final answer was going to exclude the Ai*(di)^2. Then I realized that you still have a couple of minutes left and you're doing it in a different order :P. Thank you.
Hi, this video is really helpful for me. I was strugling with this kind of problem but after watching this video, i got solution nd thanks for you dear for uploading this video on youtube.
Great video! I love the way you explain all of your steps clearly, it becomes very easy to follow! Keep making videos like this because I'm sure your helping a lot of students out.
You are most welcome. I'm very glad you've found the videos to be helpful. My hobby is collecting TH-cam hits. If you like the videos, please help me spread the word - RMF
Seriously! My professor had three of these videos, and I'm sure they made sense to everybody else. You laid it out so clearly, I was able to find my mistakes! Thank you!
Well done, nice demo, I've got some odd shapes to calculate I values for my structural engineer so he can complete a design, your excellent tutorial dredged up the first principles I learned circa 1970's, my cross sections are a combination of square and rectangular aluminium that will be used for a sun shade, I need a producer statement from my structural engineer because the Chinese supplier (bless them) have zero structural details....lol, thank you very much for perfect video :-)
Thank you sir for your help. Please keep making more videos, they are very helpfull. Please branch into thermodynamics my friends and I have trouble with that.
What is the physical interpretation of product of inertia ? e.g. in beams the area moment of inertia is resistance to bending and in dynamics mass moment of inertia is resistance to rotation then what does product of inertia means?
For Ig, how do you know when to use 1/12 bh^3 versus 1/3 bh^3 .I am looking at an example of the same beam EXCEPT it is upside down and they use 1/3 instead of 1/12.
Sir, If the centroid of the first box is the length of the second box plus half the length of the first, why didn't the centroid of the second box follow the same rule please?
That was very helpful! Thank you so much! I have a small question regarding calculating I1 and I2 at 5.43. Why is the formula bh^3/12 used?. My teacher gave me two formula I=bh^3/3 and I=bh^3/12. I don't understand which one we use and why we use it. But the video was very helpful. 2 hours of lesson explained in 10 mins. Thanks again!
This video was Really helpful. Thank You for explaining M.O.I. I'v noticed there was an error that made me "missed approach" ;) => I was watching this video without sound and noticed when at 6:20 the 533,333 looks like it says 535,333. this continues throughout the rest of the video, and my answer did not match yours. However with the sound ON, I found my mistake, and my final answer also turned out to be 3.34 x 10^7 Thanks again.
could you explain the bending stress of T,I,rectangle and circle beam ,please ? because my exam is soon and i do not know how to solve it i dont know when i have to take I = 1/12 bh^3 and when i take it =1/3bh^3 for rectangle beam for example
12 years later and still saving egineering students. awesome video
This man does a better job of teaching me in 10 minutes than my professor did all semester. Thank you so much for being clear and concise.
tell me about it

So many questions answered. Went from a ball of confusion to pure clarity. Great job. Thanks so much
Great stuff. Simple and effective. Just a man and his whiteboard with no smoke and mirrors. Thanks.
Thank You for posting this. I am an MMET student at Texas A&M and I will refer all of my classmates to this video.

You were really very precise and to the point. Thanks once again
Sir, you are a life saver! We need more people like you!
My Statics final is in a couple of days. Feeling confident but doesn't hurt to review everything. Your videos are always helpful. Wish me luck!
I'm from Brazil and I understood everything. Thank you so much to help me with my test that I have today! Great video!
Salute to such kind of teacher which makes so complicated problems into 2+2=4
You just saved my exam grade sir. Thank you very much for this very clear explanation!

Thanks Brian very clearly explaned, the force is strong with this one.

You have no idea how much this helped me. Thank you so much!!

I concur, as a undergrad I can say this was very helpful
I find the way you teach easy to understand. Thank you.
god bless you man
Wow, dude, it's just a video :-)
purdueMET you saved me in my finals :D :)
Seriously! My professor had three of these videos, and I'm sure they made sense to everybody else. You laid it out so clearly, I was able to find my mistakes! Thank you!
When dinosaurs were crawling out of the ocean....lol
lollolololol
Easy to understand than my current professor. Thank you
thank god the best teachers are on youtube :)
I can understand very clear & easy. Thankyou verymuch sir
you are such an awesome person! thanks a lot for all the help. Great video's very informative and simple to understand. God bless you.
You're a life saver , Love your videos !!
thank you so much for going over this! This verbal and visual review is very helpful for me.
Salut sava

Solid Mechanics test next week, you are da man!
I thank you , and I pray for you
I wish you the best with your career god bless you
You are the best out there. Seriously.
THANKS FOR YOUR DETAILED EXPLANATIONS.GOD BLESS...from PNG
very clear, you explain step by step..thank you so much!!
thank you very much !! good and detail teaching . totally understand the finding of centriod and the moment of inertia
great vid man. u explain everything thoroughly.
Wow. Thanks a lot. That is a very simple and explanation.
Thank you sir for your help. Please keep making more videos, they are very helpfull. Please branch into thermodynamics my friends and I have trouble with that.
@trex252 You bet. More videos on the way.
I really like all of your videos thank you.
Yes. I'm finding the moment of inertia about the centroid, so it doesn't matter if the beam is upside down.
Watch our for better understanding...
What is the physical interpretation of product of inertia ? e.g. in beams the area moment of inertia is resistance to bending and in dynamics mass moment of inertia is resistance to rotation then what does product of inertia means?
thanks for the great help for my and my mate at uni!
Good video. Very helpful for structural analysis!
for me your the great teacher "DHRONA CHARYA"
For Ig, how do you know when to use 1/12 bh^3 versus 1/3 bh^3 .I am looking at an example of the same beam EXCEPT it is upside down and they use 1/3 instead of 1/12.
You teach very well!!!
In doing the parallel axis theorem. Would it be acceptable to neglect the I term and just calculate the sum (ad^2) for the result?
Thanx a lot !!! You help me big time here !!!
I'm glad the video helped :-)
why go to uni when there is youtube and amazing teachers as this guy?!
cheers for that.. great video and really helpful
Saving my life over here, thank you!
Allah razı olsun hocam. sizi çok seviyoruz sürekli takip ediyoruz . herkese hayırlı akşamlar diliyorum..
thank you so much sir....its really helpful.
Niraj Burnwal : Bhai , vote for modi .....
You are mosssstttt welcome ;-)
Glad the videos are helpful - RMF
oh my goodness i wish you would be my professor. its just easier to understand
hi,
Ive been looking for an example for an unequal i beam looking forward
to your post for that one
Wow, very impressed! Totally understandable and well done, thanks!
thankiu very much 😍
great work welldone 👍
You're most welcome. I'm glad the video is helpful. If you like it, spread the word :-)
Excellent teaching sir
Good job mr 🤗🎩
This is crystal clear- thank you!
This was life saving.....Thanks! !
u helped me A LOT ...... thank u sir :)
Thank you so much teacher ❤️

thank u a lot u saved me from a big mistake
Only thing I would have done differently is define that you are solving for Iy and that Ix will be different. Good video though, thanks for the help!
thanks for the very use full video and one more thing can you just help me to find the shear center of the unsymmetrical sections like I sections
Great video, very clear. Thanks a lot.
Cheers mate, very well explained.
This video was Really helpful. Thank You for explaining M.O.I.
I'v noticed there was an error that made me "missed approach" ;)

clearly and understable, thanks a lot
Thank you very much! That was immensely helpful, and I really appreciate it
brilliant, very easy to understand thanks!!!
this helped me alot thanks sir.
I think there is a mistake you wrote 113mm is between them even tho it’s written 150mm ? How is that possible
Brilliantly done !!
Thanks so much for the lecture. Please explain to me how you get 170mm. Thanks. God bless you
could you explain the bending stress of T,I,rectangle and circle beam ,please ?
because my exam is soon and i do not know how to solve it
i dont know when i have to take I = 1/12 bh^3 and when i take it =1/3bh^3 for rectangle beam for example
thank you so much. I will pass strenght of materials course next term :D
ok😐
Thanx the whole thing was really helpful!
Where did you get the 1/12?
