I've been struggling for hours trying to understand this concept from my profs' lecture notes and other online videos, until I saw this video, less than 9 minutes later and I can solve all questions. Can't thank you enough!
Hey I got your attention after 2 years. One of my professors said he went to school with you. Hewes, he taught me structures but this channel really taught me structures ;)
hi structurefree. Your video was very helpful for me!! around 4:23 you start to discuss something im very lost on. I know you say not to start defining CD from the right side... but if you do, then would you say the internal force is negative? because i know you said to always define them as positive but if you look at the only external force on the right side of CD then the internal force would have to be negative would it not? or maybe i should ask. If you defined the supporting moment on the left end in the other direction, would the internal force then be negative? for AB, or would you continue to define it as positive?
No, the reason he doesn't consider the right hand side is because he doesn't want to define an equation with TD in it. In fact, he wants all the equations to be have TA in them so when he substitute the Torsion values into the compatibility, there is only one unknown (TA) and solvable, not two unknowns (TA & TD). You could try to redo this exercise going from right to left this time and thus have only TD as your unknown. The results will be the same.
Thank you so much! I find your videos really helpful. I just wanted to ask if you have any video on how to solve a question like this using the stiffness method. Thank you
Heeeey thanks a lot for this amazing video!!! I have a question that gives me two segments of different diameters and torque between them is given.. it is fixed from both sides how can we get the other diameter if we are given one??
Hi! Your tutorials are wonderful. Thanks a lot. Do you have any lectures on Torsion without constrained warping that uses St. Venant's Theory of Torsion? Also, do you have videos on Work and Deformation energy? These would be really very helpful. Looking forward to these videos. :) Best Regards, Poulomi.
Why is it that the distributed load in segment AB is t*x and not (1/2)*x*t, like we do in other examples? It would be considered linear. I always thought this way made more sense than multiplying it by half because its linear in whatever case, triangle or not...
When he was drawing the Diagram for T(ab) he said to take T(ab) to always be positive? Did he mean to say to take T(ab) to be in the direction of the distributive torque? Since it is cutting through the distribution, wouldn't it be the same direction?

Thanks for your comment. I wish you the best in your academic pursuits.
You are a mechanics God
Damn I was going to say that...
Duude youre a beast. Finally someone who can articulate themselves quickly and clearly.

Yo I've seen most of this guys videos and I'm convinced that this is Aziz.
2:20 Why is the angle of twist at point A zero in relation to point D?
because the ends are fixed the shaft cant change its position and orientation and hence the angle of twist is zero.
thank you dude...help me a lot..will ask my friends to watch your video
This is great. Would love a statically indeterminate compound shaft with torque loading.
Great job! I really appreciate your teachings!
Hello I have a question. What if i have a bar of material A in a bar of Material B, can I apply this method and how? Talking about torsion of course
please do an example in which the direction of angle of twist in a section is different from other sections. thank you

Awesome freaking video man
Heeeey thanks a lot for this amazing video!!!

In minute 7:17 does not x has to multiply TA as well. (TA-5)(x)
Really good stuff man ! keep up the good work
your pretty awesome. :) thank god for youtube and smart people!
why do you multiply the distributed torque by one meter? thanks
VERY HELPFUL!! Thank you so much!!!

Poulomi D I don't have any lectures on torsion using st. venant, but I have a few on virtual work for deformation calcs on beams.
structurefree Thanks for replying. Please could you send me the link to virtual work cal. videos then. It would be very helpful.
Regards,
Poulomi
AWESOME!!
Thanks! This helped me out perfectly
You are welcome!
is it possible to solve for the reactions A and D by superposition for compatibility? similar to the Flexibility or Force Method of analysis?

Oh my god you are my SAVIOR-- a student panicking in the library 2 days before her exam
Wonderful!
I can't thank you enough!
Excellent!
Can you please explain how to find the angles of twist at points B and C.
you can not because it is fixed ,so angle of twist is zero in point A and B.
Thanks i wan confused about steps.
Thank you
Thanks...
thanks
wait for it....
will you ever do a face review??
oops doesnt let to give the image link of the question..
i love youu 😊
structure freeeeeeeeeeeeeeeeee
i love you
TAKE A EXAMPLE WHERE TORSIONAL RIGIDITY CHANGE.....
ary
i luv u
