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!

[@unhealthycasuistry]

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.

[@amyzhao6427]

"that's a nice flange you got on your beam there hehehe" (with the eye rolling) hahaha🤣 thank you for the amazing videos!!

[@amo_res9266]

Finally an engineering video in ENGLISH! With American Accent.

[@gregbrown1695]

LMOA word!!

[@Hittingthegriddyliterally]

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!!!

[@hornyhour]

you the best lecturer ever... You deserve an award..👏

[@vondermout]

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.

[@tayylewis]

you turned something that made no sense into the easiest thing ever in statics, thank you

[@manuboker1]

Wonderful solids lessons!! really taking the time to explain the problems along with a good sense of humor :))

[@imrnshkr]

I have mechanics of material examinations tomorrow, god bless you prof jeff

[@Haffy442]

Bro you gotta study earlier

[@thecowcowclash]

Haha I do the same thing as you did at 14:36. It also makes me chuckle whenever I do it.

[@1234jhanson]

Thank you, I love you too

[@Trimmdeuns]

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

[@SabinaSaby-r7p]

Thank you

[@shafiqrezal2855]

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?

[@MdAlvi-cw3bn]

You are a lifesaver !!!

[@NullPxl]

Thanks Jeff

[@tevinabeysekera6038]

Thanks so much for the video!

[@ranasherdil8843]

Why was Qa and Qb calculated differently?

[@user-xd4md1ts8n]

Thanks a lot :)

[@LifeofFarhan]

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?

[@askmobashawiralam9630]

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.

[@user-hy2vk9vv2p]

Why thickness if c is 200 not is 20

[@josie.larinni]

hi! i have a question. when do you use I=(bh^3)/12 and when do you use I=(bh^3)/12 +Ad^2?

[@Benediktus-uy1ck]

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

[@josie.larinni]

@@Benediktus-uy1ck thank you so much

[@maryckbuilds]

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.

[@liamapars2816]

Is the MOI formula different for other shapes?

[@maryckbuilds]

Yes, but generally, in this topic atleast, it's usually rectangles

[@haziqzafran8562]

Maseh dr jeff

[@JohnFMann-yz9bw]

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.

[@kyleburgess7634]

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
