[@emintorabi7115]

This absolutely amazing. I enjoyed strength of materials for the 1st time in my life by watching this.

[@FB-bf1ww]

Its been just over 3 yrs since I graduated college, but I had to review some stuff I haven't done in a while so I found this video. I used to watch your videos when I was in college, and they were always so helpful. The way you talk and describe stuff always cracks me up, so funny. Puttin a little humor in engineering, BOOM 🤣, thanks man keep up the good work! 👍👍

[@FB-bf1ww]

And I always thought you said "structure freak", not "structure free" lol, did you change this or was I not paying attention?

[@structurefree]

@@FB-bf1ww Ha! It was always structure free, but I like structure freak, maybe an alter ego.

[@clasphinx]

Sir, you just saved my final exam. Thank You.

[@matthewadams9481]

I love the energy you have in each video! It somehow gives me energy to keep studying all night. You are the reason I won't fail this class

[@mohammedbinopata9977]

legend. So much better than auckland uni lecturers. you are a hero

[@berkleyposalski8079]

i know like i'm 2 years late to the party but damn my Str of Mats Professor is so monotone and depressing so i stopped going to lecture but this is some of the best content on KZbin strictly for the energy level. Helped me so much!

[@noshinnawar8210]

Your videos are amazing! My professor recommended your KZbin channel and these videos help fill so many gaps in my knowledge!! I'm definitely going to leave this class with a much better understanding thanks to you. Thank you!!

[@siyunchinn3904]

I like the tone. Structure mechanics is not boring, it just depends how you explain it. Good job!

[@theaquifer]

Your presentations are THE most helpful mechanics study aid EVER. Thanks bro!

[@benengleman1707]

Excellent video, keep up the good work! Us engineering students are truly grateful for your work, sir.

[@omrslmmss]

Structurefree is literally the coolest dude ever. Awesome videos, great content, and super rad dude! Much love man!

[@meteoriter1647]

22:33, three boards no nails, you don't have a beam, Son! Hilarious and also genius explanation style, thank you, structurefree!

[@bmanc2000]

This is great! I didn't know if I was going to be able to learn strengths with all my classes moved online, but this is an amazing lecture with great explanations!

[@nadeemshaikh7077]

Ur energy is juz lik an feather on hat to the amazing way of teaching 🙌😍

[@abhishekjoshi8413]

you really are awesome i have my entrance exam and this is really helping me for my revision and concept clarification. Thank you and keep up.

[@anbumadhan7735]

Wow.... clearcut explanation 👍👌

[@ootiminatoroo421]

"You don't have a beam! Son you just got 3 boards!" - 22:32 lmao

[@diegt7846]

Had me weakk!!!!!

[@firozfaroque7521]

Great video, u gave a 3d understanding of shear stress :)

[@structurefree]

thank you!

[@GungnirStrike]

you are an incredible wealth of information. THANK YOU.

[@seyfe311]

yes you can weld aluminum. U need alternating current to break through the oxide layer. And btw thanks for all your videos! keep up the great work, structurefreeee

[@abhishekudupa3818]

Welding would compromise the heat treatment

[@anroquibz7152]

long live structurefreeeeeeeee

[@structurefree]

AwwwwDjyeah! Structure-fuh-reeeeeeeeeeeeezzzzzyyyyyy.

[@Prando34]

This video was incredibly well explained! Thankyou very much

[@mustafacakr7034]

man you are much better than my professor thank you so much!!!!!!

[@victordinizlopes393]

Congratulations for the great explanation!

[@mattchesebrough4050]

Love the energy! This has been a great video. Thank you so much for posting. You rock!

[@kent6944]

Man you are better than my lecturer

[@power-sp3km]

my god , I love this man so much

[@dilgoran]

Great flow on explanation. Thank you.

[@mbalenhlembina373]

Thank you so much, you are amazing.

[@husseinalizereej]

this is a very helpful vid thank you. if you understand this 27 min u should be good for chapter 7 and little from 11 and 12 for beam design

[@mohammadazraazriazhar2170]

Thank you for doing what you are doing. God bless you :')

[@markusaurelius4015]

Fantastic video! I hope you keep this kind of content up! :D

[@Romeo2710Oo]

STRUCTUREEEFREEEEEEEEEEE I was about to fail this year but you got me :D :D :D :D

[@ranjanbogati8990]

thank you, you made me understand clearly

[@thacrackfox]

Congrats. you have hibbler solution manuals and are super excited about it I see.

[@qiesmalkawi6139]

amazing, god bless u ,my respect from jordan uni of scince and technology

[@structurefree]

+qies malkawi thank you!

[@caragioiu]

Excellent. Love watching your tutorials. Maybe you could squeeze in one of these days a bolted connection subjected to bending moment and determine the shear load taken by each bolt with respect to the center of gyration?

[@wynandvanwyk9861]

Leaaaaaarning!!! Thanks so much man :)

[@omarnabet7979]

this dude reminds me of "Annoying Orange" it is hilarious! Love it

[@Mbibi1261]

Mannnnnn you're fucking phenomenal, god bless your soul

[@alishad9777]

So glad I found your channel, your videos are awesome!!! Thank you! Can anyone give insight on what we would do for a similar shape but with multiple nails in the top and bottom beams? LIke 2 or 3 nails going left to right across the cross-area section.

[@joshuakravitz1524]

Thank you so much for this video! My professor should watch these videos to understand how to teach! Also… since when could you not weld aluminum?

[@structurefree]

Thanks for the comment. I should correct the video and say that there are some aluminum alloys that are not weldable.

[@siyunchinn3904]

I don't know F150 is bolted instead of welded, however, aluminum is more difficult to weld than steel, and more importantly, a welded aluminum structure has much less strength than a bolted aluminum structure.

[@SHIRISHHC]

@23:46 shouldnt the distance from NA for the bottom flange be taken as negative 90mm? and shoudnt we be getting the first moment of area 0 again?

[@kaushikmadishetti7940]

It was a great video thanks for uploading. but how did you consider force allowed is 650N .

[@rayanelsouki6748]

You are legend

[@briang2340]

This video is great. The only follow up question I have is do the screws need to be at the same spacings along the full length of the beam? Or can the spacings be increased in certain areas to make it as efficient as possible? For example, can the spacings be further apart at the ends where the moment is smaller or at the middle where the shear is smaller.

[@structurefree]

I guess you could vary spacing...it might create too much opportunity for error on an actual project depending on how many variations you have

[@vilivont4436]

Just great

[@muhammadsadek5525]

Thank you very much, but isn't the bolt supposed to be through the flange to the web?

[@김세라-e6b]

I really loved your video! I was able to go through your video without being bored. But I have one confusion, could you tell me how you calcuated 650N for F-fail? (If it is given, do you happen to know the equation to solve for it?) once again, thanks for such an awesome video!

[@Rafael-rk4mn]

Hi, I'm a civil engineer here in Brazil, I do not speak English so sorry for any possible mistakes. I would if possible to clarify a question, in the video you are addressing shear connectors that can be used to support metal beams in solid slab of reinforced concrete? if it is not the same calculation would have to say if it is possible an adaptation or if you have an electronic address with an apostila .. do you have any video or handout that has an example of calculation of connectors formed by sheet metal folded welded in the metal beam?

[@DolfocarAli]

Thank you for the excellent lesson I have questions “what is the program you are using for writing”

[@Feri9]

nice video,but at 22:32 when u say the Q is zero for the down connector it is not zero actually because according to another video of you u should add the whole area of above so means u should add that up flange to that zero which gives u the same result!

[@ehsanmohammadpour7670]

faran bezar darsemoono goosh bedim inghadr harf nazan. :D

[@nadeemshaikh7077]

Exactly 👌

[@gallie2009]

Great video! I've sent a few people here because it explains shear flow so clearly. Q for you: how would you look at the shear flow for the connection for say a 4"x4" box to the inside flange of a 10"x10" box when it's inserted into the 10"x10" box? Would you treat just the flange of the 10"x10" box as A' ? Or does it even work like this? My profile pic is an image of the example XD

[@structurefree]

I think you'd have to treat all of the 10x10 box as A'.

[@kanishkrauthan2470]

Great Video Man,I have a quick question though, when calculating 'Q' for 2 shear planes, why did we not take the distance from the NA to the center of the bottom flange as '-90' since the positive y is defined above the NA which makes anything below it negative? thanks :D

[@sonicboomman2008]

You can weld aluminum. Just saying. Love your channel!

[@mattyou6381]

fire outro thank you lmao

[@RogerDiotte]

LOL at the beginning lol...Cool moments with math lol!

[@sondraraharja2755]

Thank you structurefree

[@structurefree]

+SONDRA RAHARJA you are welcome!

[@anroquibz7152]

btw sir, can u hav some example problems in steel design ( bearing, shearing and tensile str. of riveted connections etc.) please? i really need to understand more in this subject. pls..pls..pls...pleeeease?

[@alessandromarialaspina9997]

When you say Neutral axis, that is incorrect. The neutral axis is defined by the general flexure formula by resultant bending moments. What you mean is the axis of the center of gravity for the cross section of the beam. Let me know if I'm wrong.

[@hazzellonzaga7444]

kudos!

[@akshitvashishth5481]

Why didnt you put y as -90mm for the below area while calculating Q using 2 shear planes ?

[@AdaamTube]

Thank YOU

[@chain3519]

I love you, thank you.

[@virajfernando2694]

How did u get 650 N as the F allow? Thanks in advance. And Love your videos :D

[@nickthien97]

Please do a question that explains how to find the Shear Center pleaseee

[@MisterBinx]

On some examples I've seen I have no idea which area to use. LIke a hollow square cross section with nails at each corner. My book doesn't explain it.

[@MTB-Josh]

Structure Freeeeeeeee. Can you do some videos on the Energy Methods?!

[@structurefree]

+DeeZ154 like virtual work?

[@structurefree]

thanks!

[@amirmaghsoudi9269]

Can someone please explain why we took v to be 3KN instead of integrating the flow function -2* X*Q/I from 0 to s and equaling to 650?

[@FawazBnMohammed]

why you gave only one example which is the most easiest example for the whole subject

[@sunz.6072]

I love you

[@SAINIVEDH]

So we need 67 bolts

[@xandersafrunek2151]

I think the final answer should have been 22.5 mm for one shear plane
