Started watching you since statics when I was on the brink of a degree switch, I am now 8 classes away from obtaining my MECHANICAL ENGINEERING degree and it is all thanks to you! God bless!
I am a relatively young faculty of civil engineering from the Philippines. In my nearing a decade of teaching, I never handled strength of materials. I now find myself having to handle review classes for the course and your lectures are literally blessings. Perhaps more importantly however, the way you discuss is something I hope I can later on emulate. I hope you don't mind me referring my students, both current and future, to your videos. Thank you kindly sir.
Recently found you while studying for a mechanics final and I would just love to say how appreciative I am that you post these videos. You explain the terms and their origins so thoroughly. It makes the class seem so much easier. Thank you so much!!!
thank you Dr. Hanson, your videos are very good, your students are very lucky. I am structural engineer, and i was wondering if you would ever consider making a video on shear lag? this concept has always seemed rather complicated and it is hard to find good papers on the subject.
This is beautifully done Dr. Jeff. Your lectures are definitely helpful. I've been following your lectures for my assignments in Cranfield University, England. Please can you do me a favour, sir. What would be the shear stress at a point on top of the upper flange? Is it zero or not? Pls explain to me
You use +AD² if the neutral axis does not cross the centroid of your piece part of interest. In this case the flanges of the beam. The neutral axis crosses the web's centroid, thus you dont need +AD² for the web
I know I'm 4 months late but for anyone else who may be wondering why to Ben's ans: If you use the full equation, you'll find that if the centroid = neutral axis (ie d = 0) then that whole side disappears and you're left with just the LHS.
Sir.. Please Solve the problem no 6.32 of Bear and jonson 7th edition mechanics of material. There I am facing problem to determining the thickness. Please help sir.
Wasting time and giving incorrect impression of importance by calculating large numbers to two decimal places..........ridiculous actually. More important, total shear force on each area that Q is calculated for should at least be discussed......even better if calculated.
This is an educational video for engineering students he’s simplifying the numbers for the sake of the video. He’s not calculating stresses for a million dollar building he’s teaching based off of what’s in his textbook. Grow tf up

So many engineers bow down to this man. Much love papa hanson
Love you too buddy!
nah the meat riding is crazy
@@lilbit7288 man before you comment something like this remember that your account is public 💀
@@lilbit7288young fella, delete ur comment or vids b4 it comes back & hunt u one day.
"that's a nice flange you got on your beam there hehehe" (with the eye rolling) hahaha🤣 thank you for the amazing videos!!

Studying for my FE. This man is a saint.
you turned something that made no sense into the easiest thing ever in statics, thank you
I have mechanics of material examinations tomorrow, god bless you prof jeff
Wonderful solids lessons!! really taking the time to explain the problems along with a good sense of humor :))
Iam immensely benefitted by your teachings Jeff
Haha I do the same thing as you did at 14:36. It also makes me chuckle whenever I do it.

Jeffy Hanson my best lecturer, take your flowers🎉
Thank you, I love you too
i was crying before watch this vide,. Love you Mr. Hanson :,)
Finally an engineering video in ENGLISH! With American Accent.
LMOA word!!

YOU FORGOT TO SQUARE D
Thank you sir, ur videos are fantastic. U helped me a lot!
Thank you, Jeff!
"is that with 2 cc's or 1 Q" 🤣🤣
Great stuff. Thank you
9:50 why didn't you take area from section 2 ?
Why would one subtract there on moment of inertia? What might be the reason to subtract and not add?
You are a lifesaver !!!
Thanks Jeff
Thank you
Let's say, you put in the exam, the beam and we find SF diagram and bending moment diagram. How can I know which has the highest shear force?
hi i have a question. do the points A,B,C and D have to be determined by students? or are they given on the diagram?
Thanks so much for the video!
Thanks a lot :)
Is the MOI formula different for other shapes?
Yes, but generally, in this topic atleast, it's usually rectangles
hi! i have a question. when do you use I=(bh^3)/12 and when do you use I=(bh^3)/12 +Ad^2?
You use +AD² if the neutral axis does not cross the centroid of your piece part of interest. In this case the flanges of the beam. The neutral axis crosses the web's centroid, thus you dont need +AD² for the web

Why was Qa and Qb calculated differently?
Qa you need to account for the 2 different rectangles while on Qb, below it, there's only one shape
Why thickness if c is 200 not is 20
Maseh dr jeff
