Can i just say.....YOU ROCK!!!Im busy with Civil engineering at the University of Pretoria (SA) and everytime my friend and I have no idea what our lecturer said we both just say "StructURE FREEEEE LEEEEEEEEEEEEAAAAAARNING"
so much better of an explanation than most of the professors out there explaining this stuff - i'm trying to grasp combined loads for the P.E. and I think this is one of the first times it made sense to me so thanks!
Hey, maaan! I was just thinking that why all the professors confuse students minds but most of the youtubers explain this topics better than they do. How can it be possiblee ? whateverr! BAAMM! STRUCTREFFFFFRREH lööninnggg! You da best!
What about if you placed A on the other side? (At 1:15, A is on the right side of the rectangular beam). Im doing similar problem with a circular cross section and shear stress opposite sign on each side, not sure why
These videos are great, and they've helped me pass my CE 204 class. I do have a slightly unrelated question though Do you think you could upload your work sheets in the discription of the video? I try to follow along, but sometimes you pull back values or equations from previous pages and I have to backtrack in the video to find what you're talking about. It would be easier to work alongside the PDF. Idk if others get this too, its just a helpful thought:)
Does V always have to be stated as pointing UP on the negative side of the cut face. I was taught V points down, which would make -V - 2 = 0. So V = -2 (downwards)
Amazing video.. in the end; when computing the direction of the stress by moment, did he take the direction of moment wrong,isnt it down to up ? Shouldn't the stress be tension because of the direction of moment?
You said internal shear is positive upward on the right. I realize it's arbitrary but according to your FBD I think you meant positive upward on the left?!
Finally...Structurefree has come back to TH-cam...In front of the millions and millions. So if u can sammelllalalalalalala, what structurefree is cooking! [Interview Scenario] Structure: So, what did ur candy-ass learn today? Me: Well..ummm, I kinda.... Structure: It doesn't matter what u learnt!!
The sign is there to denote the direction. You could ignore the sign in the calculations as long as you address the direction in the graph or in the final result.

+eckard degoede Ha, Ha! Ahhhh--yeahhhh! "X gon' give it to ya!"
From University Of Johannesburg South Africa... Thanks a million times... Was really confused in class but this...

such a boss! Aced my solid mechanics exam because of you! Keep doing what you do!

whateverr!
BAAMM! STRUCTREFFFFFRREH lööninnggg! You da best!
Dude you fucking saved my sorry ass. In my final year of engineering and my uni don't explain shit. THANK YOU
THANK YOU!!!!!!! Learned more from this video than the lecture notes :/
At 8:20, you decide to take the first moment wrt the bottom area. My question is how would you find Q with the upper area?
What about if you placed A on the other side? (At 1:15, A is on the right side of the rectangular beam). Im doing similar problem with a circular cross section and shear stress opposite sign on each side, not sure why
Okay man, if I get an A on my final, you are getting a donation of 21$. You have my word.
Did you get an A on your final?
Mahutin Ligan haha. +1
RADHIKA NARANG Uh...not sure if that's happy laughter or nervous laughter lol
Lol I like how you specifically donates . 21.
mind of an engineer
Thank you for making this subject way more understandable. I'd say "I wish you were my professor," but at this point you practically are :'(
Awwww djyeaaaah, Professor Structurefree!
Should it be -2knm for the internal torque at A, and the normal strees be positive (tension)

Thanks your lesson is very helpful
Hi, how to determine the sign of convention of torsion
Should the cross sectional area be equal to 500 mm * 150 mm (.5 meters = 500 mm) ?
Sannisha Castillo i had it set up as 50 mm * 150 mm. (50 mm = 0.05 m).
how do you calculate the stress on the y? I mean sigma yy
You said internal shear is positive upward on the right. I realize it's arbitrary but according to your FBD I think you meant positive upward on the left?!
Really, really good videos.
hi... it really great video ... i have a question what if the cross section was ( I ) shape ?
Thanks. It would change all the area properties.
Man god bless you
Why dont we have to calculate the reactions?
Finally...Structurefree has come back to TH-cam...In front of the millions and millions. So if u can sammelllalalalalalala, what structurefree is cooking!
[Interview Scenario]
Structure: So, what did ur candy-ass learn today?
Me: Well..ummm, I kinda....
Structure: It doesn't matter what u learnt!!
I can't believe it took me 5 years to see this comment. Soooo funny!!! I'm starting my classes like this from now on.
why did you not calculate the moment of inertia at point A?
when finding the transverse shear stress
Where are the subtitles?
ARIEL ADAEL not sure. I thought youtube auto generated them? Hmmmmm.
i always say with him "stricture free L E A R N I N G"..:
Thanks. But why did you use M = +2kN.m instead M = -2kN.m

Good video!
this 12 minute video taught me the same amount of 10 useless 1 hour long lectures.
You got me at hello.
Lmfao at the beginning
You should add videos explaining the thought process instead of just examples...
Yeah now it's correct Man U had V equals 4 last time
SolidWorks tutorial for the same problem, here th-cam.com/video/ArTRJhA9dJ0/w-d-xo.html
fadoob
moment is calculated false, true is 2*1+4*0.45=3.8knm
No he assumed the 4KN force was going right through the the centre so it's 2K *1 + 4K * 0= 2K N.m
