well done for such a good explanation
Hey its amazing explaination, but is there any chance for me to have your references? It'll be great!
WOW!! When I was going through university 30 years ago, I couldn't grasp this. You made it so logical and straightforward to understand the way you developed the idea. Impressive...Thank You so much.
Learned more from your first 7 videos than I did in 4 years of engineering and 25 years as a P.Eng. You actually make it look easy. You're impressive.
Thanks. Good Job
Thank you too!
still waiting for your next vid :)
Thanks a lot for this video, very clearly explained! Keep up the good work 💪
Great Video.
Thanks!
Thank you sir Great explanation of section modulus Cross sectional property of material in elastic range to oppose bending.
great video, thank you!
You are welcome
Wish I had a teacher as good as you ❣️
Thanks!!
I think you're doing a very good job of explaining things slowly and calmly. Keep up the good work!
Thank you very much
Thanks for support
You are welcome
Hi. Thank you for your videos. When you intridoce shear force in minute 13.00, some books assume that the sum of moments must multiply the shear force by deltax/2. Could you kindly let me know why is shear force multiplied by deltax/2?
Thank you so much...
You are welcome
Are you sure the cross section rotates clockwise?
Sir salute u from Pakistan. Ur lectures are adorable. Sir please upload further lectures....
I will. Thanks!
👍
👍
It was difficult to find a video explaining practical application of Plastic Modulus, and you nailed it!
Thanks!
It’s okay we’re very thankful for your efforts.
Great tutorial video. Thanks.
Thanks!
I enjoyed your teaching
Thank you
Honestly, this was a very good video. There was no jumping of steps. I really appreciate it.
Thanks!
Thanks!
An excellent explanation though... I haven't seen such videos on internet ever... Really appreciate your work.... Do we have other parts as well?
Excellent Ike Excellent
Thank you
You are welcome
I know I'm late to this, but this is an excellent video.
Should it not be a Sine curve?
New Subbie!!!
Comments and Likes for the alogorithm! 🌸

Yo
Awesome Video sir, Hatsoff to your style of Explaining. Just one doubt I have, correct me if I am wrong but, the derivative of cos w (t )=-w sin w(t), is it not?
No, because w is a CONSTANT in this case

Hello 👋🏻 Sir, Loads of Love from India. You are a great teacher sir, I studied my Engineering and many Concepts were not clear even after working for many years, but in just 2 classes of yours those concepts are clear. Hope you are doing good, you promised the videos will come regularly but, 🙁 stopped again . Hope everything is fine with ? Please reply and upload the remaining Dynamic classes sir . You are a great teacher and a beautiful Human Sir, Many many Thanks !!

How much factor of safety to be considered for A36 steel to find allowable stress ..I considered 4 Safety of factor and max allowable stress as 62MPa.
This is something that the particular jurisdiction code will prescribe depending on bending, shear, compression etc.
Check out the latest in the structural dynamics series. th-cam.com/video/92pA9aG8Usg/w-d-xo.html
Hi sir ..there is two question in one of my exam ..they asked to select the correct A36 steel Universal beam which can carry 150 kn-m moment ..and also they given four options of UB sizes with Sx value ..how can I find it ..I tried same procedure to find Sx as u mentioned in this video but Sx value not matching ..I have considered allowable stress for A36 63 MPa and 150 knm moment they already given..but my final answer coming .please suggest 2419cm3 ..but all option is like 780cm3 , 569cm3 like that ..please help In this
The was the shape of the beams?
Thank you very much Sir

Perfect video. Thank you 😊
You’re welcome 😊
I'm really late to the party, but I wanna ask. As far as I can see, the sigma1 formula only stays true for elastic stage of the material, so would the shear stresses formula. What'll happen if the cross-section approach the plastic stage? Will the formula change? If it does, then what is the universal way to calculate?
Correct. The video on the plastic section m modulus will give you the clue as to the manner in which the formula changes

Ike I am a young structural engineer and I have found your videos incredibly useful.Very concise and to the point. In particular the two videos about structural dynamics has helped me improve my understanding on these advanced topics as this is something I had previously struggled to understand. I can't thank you enough for putting these videos out.
Thanks a lot
Appology accepted. Keep up the good work

Very good and instructive video. Could you please provide me with the references from which the material was drawn?
I hope all is well! I am waiting for the next part of this series! I thought it was a "fresh start" with a "streamlined system." Thank you!
Next video out in a few days :)
