Shouldn't Atheta,in also be trapezoidal area ?
Too complex 😢
Can you tell the name of software/application that you use to write ?
Amazing!!! I am really impressed by your explanation. I took plenty of notes, screenshots and everything you name it.
thank you so much ... could you done by the second way (D. fluid element )... please...
There won't be a tou xx in x direction equation. It will be zero.
I think in theta direction Taylors series is wrong
It’s very helpful! Kindly guide for doing this derivation in spherical coordinates also
Yes Sure!
best of best
Sir, I believe you have a sign error at 12:33. You rewrite the equation for F_s,r without the pressure terms that cancel but you change the sign for d(Tau_theta,r)/d_theta)(dr d_theta dz) from positive to negative
I agree, and I believe it should be positive according to the initial FBD.
are you a professor?
Hi, yes.
Amazing video, greetings from Germany!
Thank you for comment!
In part 3, the figure is correct, but when he derives the shear in theta-r direction, the sign in front of theTau_ theta-r should be "-" not "+". (See time 4:28 min.). Ultimately, it results in adding two shear terms (see 8:14 min) to get (2/r)(Tau_r-theta), which is the correct answer. The final result is correct. What am I missing? Please show my mistake, if any.
Make more videos sir
You must remove your name from video : it is disturbing !
Ok.
excellent, i have a question: what apps o software use to your slide? Best regards from Peru!
Thank you for your review. Notability is the app.
Its extremely helpful! Good work!
Thank you very much
Hey can i hire you? Lol
Good work!
Thank you
I loved your video! Which book do you suggest me to deep more in this topic? Thank you so much
That way all are good but conservative form is not derived in any text, most of them have derived in nonconservative form and then deduced to conservative form. As far as books are concerned: if you are beginner then J D Anderson of Versteeg - Malalasekera is what I recommend for my students.
@@mayureshwaracademy513 i noticed that too.. do you have any idea why does all the text usually explain the non-conservative form first then derived them to conservative form? I'm curious
Great explanation! Congrats. By the way, what kind of tablet are you using for your videos?
Ipad
Excellent
Thank you for reply.
You are brilliant!
Thank you so much.
We miss you sir!
Thank you Aditya- I also miss you all
Thanks! Great explanation.
Thank you so much Chris, you are true inspiration. Your comment means a lot to us.
