moment of inertia of area T bar

[@fastline100]

Fantastic set of videos. Really clear and well explained. Keep them coming!

[@yggokl7856]

There is nothing to say, you are my heto. Thanks 😍

[@akusyima]

I am not sleepy listening to your voice sensei. thank you.

Syima Abas you're welcome, gakusei.

[@i6tir]

Thanks! I hadn't done this in a while and was looking for a quick review. This video is just what I needed.

[@virtually_passed]

Glad you liked it!

Hey mate, calculating Ix (the moment of inertia about the x axis) for a rectangular bar (of base b and height h) about the center of the bar you will get 1/12 bh^3 I think you might be thinking of Iy (the moment of inertia around the y axis). I hope that helps :)

[@taruntej9146]

That's an amazing explaination maan thanks alot🔥

[@krishantiwari9294]

Very well explanation.. thankyou

[@ozcanozgur432]

I understood both english and t bar subject :) your video is more useful than videos own language :) thank you

[@chepkiruikosgey4315]

Hey could elaborate on when to use use ⅓bh³ and 1/12 bh³ because there's a video you've used the former.

Awesome man thanks

[@virtually_passed]

No worries!

[@quocaoang7343]

thanks

[@SeraphisQ]

What a god! Thanks!

[@salmamedhat241]

that was so cool but i have a kind of stupid question? .. why did we get Ix and not Iy ?

[@virtually_passed]

+Salma Medhat Hi Salma! I_x,c is the moment of inertia of area of the centroid about the x axis. We could evaluate I_y,c if we liked. The process would be really similar. I personally decided to calculate I_x,c because that's usually the more helpful figure when calculating normal stresses due to bending - but you'll discover this in later courses! :D

[@salmamedhat241]

+Matthew James wow.. thank you so much! the video really helped. 😊😊👍👍

[@virtually_passed]

If you have any more questions, let me know :D

[@salmamedhat241]

+Matthew James +Matthew James hmm since u asked. 😁 I was wondering if this cross section is subjected to a compression or tension force how do I calculate the stress and does the stress changes if the cross section is hollowed ?

[@virtually_passed]

Hey there Salma! We're really getting into the heart of mechanics of materials now haha. The answer depends on where and in what direction the forces are acting. In short, if the beam is under regular bending then there will be normal stresses both above and below the neutral axis (specifically tension below and compression above). The formula is My/I and yes, the stress will change if the section is hollowed. I can't go into much more detail than that without because this is a completely different course subject haha and I'd need a full diagram :P

[@saisantosh9825]

Sir I have small doubt .sir how to find the moment of inertia if left upper part of t section is not there and only lower and right portion is there then how you find the moment of inertia( it looks like reverse of 7 number but not L have you understand the question sir

[@KasraDaryani]

it was awesome !

[@hiteshchauhan4154]

thnq so much sir

[@virtually_passed]

You're welcome, sir :)

[@杨勇军]

wow，great!

[@arvinm10200]

thanx man! really helpfull

[@virtually_passed]

:) happy to help!

[@ayoubgm8011]

thanks ;)

[@cwill6491]

Why does everyone keep confusing this for moment of inertia...

[@virtually_passed]

Hey mate! Frustratingly the second moment of area (units = m^4) is also referred to in some textbooks as the moment of inertia (units = kg m^2). Even though these terms are very similar, you're right, they're not the same.

YOUR THE BEST MAN. IM WRITING A TEST IN 12 HOURS, MY LAST MINUTE PREP IS TOO AWESOME

[@virtually_passed]

+TEAM PRIMO Glad you found it helpful, mate!
