thanks brother really helped alot My teacher made 1 hour lecture on it and i still couldn't understand anything after that lecture you cleared everything in just few mins
In the example problem, only the shear stress between the topmost plank and the one beneath it were shown (which was 8.15 MPa). Calculating the other glued parts: Shear Stress between 2nd topmost plank and the one beneath it = 8.97 MPa Shear Stress between 3rd topmost plank and the one beneath it = 7.61 MPa If my calculations are correct, it shows that the most critical area was the glued part between the 2nd topmost plank and the one beneath it (since 8.97 MPa is the highest among the three). Although the answer will still stay the same (that the glue will still hold), it's important to note that the critical area might not always be at the topmost boundary depending on the cross-section area. ^I'd appreciate if you would verify my understanding of the problem. Thank you for the lectures!
You are a wonderful instructor and make great videos. Could you please avoid using the bottom ~15% of the screen; if you pause it @ 09:27 and try to follow the math, the equation is covered by the video controls that show when the video is paused :/
Can you kindly make a tutorial video about how you create these lecture videoes? (Including what application you use for writing, for audio and video recording and also) Btw your lectures are really awesome 💙
Hi, my best bet is that he uses Microsoft Whiteboard (or some kind of equivalent software) for the writing part. It is either done on a Surface tablet or on a regular computer with a graphics tablet. Then, any kind of screen recording software could be used to capture the screen in real time (there are a lot of good options here but OBS is a powerful and free one with lots of tutorials online). Since the screen recording is sped up, the audio must be recorded separately with Audacity for example (free and really easy to use). Lastly, everything is combined in a video editing software and exported for RUclips. Davinci Resolve is a really powerful video editor even in its free version and there are a lot of good tutorials on youtube. While I can't be 100% sure about the software he uses, I'm confindent you could achieve the same result yourself and for free with all the software I mentionned. Good luck !
did you need to use the parallel axis thm or can you also find inertia normally by adding up the 1/12(b)(h^3) for each section? (and if you cant how do you know when you have to use the parallel axis thm?)
You can split the geometry into vertical rectangles and not have to use the parallel axis theorem. You know the parallel axis theorem has to be used when you cannot split the cross-section area geometry into shapes that ALL have their centroids on the same axis as the neutral axis.
Very good synopsis and actually glad you go quickly. I can always rewind as necessary!
thanks brother
really helped alot

you cleared everything in just few mins
Glad it helped
wow this is one if the best explanations veidos I had ever seen. keep up the good work thank you.
you're a genius! my Good Sir, simple and straight forward content, keep doing the good work!
The auto generated subtitles on this are wild 😂

Yup, you got it right. The question here was the glue where the arrow is pointing towards, but your analysis is correct.
@@LessBoringLectures Oh my bad! Thank you for verifying the analysis though :D
Wow ... this video is a piece of art!!!
Thanks! :)
Thank you sm. This shit is too crazy. My guy really clutched the brainwaves in my skull. Legend.
Thanks man, had a hard time understanding this conceot from the book, you made it quite easy
Example in the last few minutes was just awesome 🔥🔥

Thank you. That was a great lecture
Thank you Very much you are an excellent teacher!!
You are welcome!
Oh gosh! You are really amazing!
You are an amazing man!!!
Hello, which software is used for whiteboard here?
If instead of glue, the planks were held together by nails, how would the expression change? thanks
can you tell me the reason as to why is there a horizontal reaction and vertical reactions at the cut?
Can you kindly make a tutorial video about how you create these lecture videoes? (Including what application you use for writing, for audio and video recording and also)
Btw your lectures are really awesome 💙

Thanks @@gauthierf
Thanks a lot!
For I3 how do we get a base of 90 m? When I was looking at the problem I thought that the base for I3 would be 60 m.
Thank You!
way better teaching compared to the university professors
excellent

Great video. Very fast though lol
