Mechanics of Materials: Lesson 51 - Mohr's Circle for Stress on a Plane and Elements

[@jd4571]

I just want to say Dr. Hanson is the man. 100 on the midterm for the statics portion thanks to him. Got the final in mechanics of materials/statics in two weeks. This playlist has been extremely helpful. Thanks Dr. Hanson!

[@smartereveryday]

Rotate the X Side to the plane… got it!

[@SubparExperts]

Love the videos Destin! hope the PhD is going smoothly.

[@balikis]

Nice to see you here

[@andrewzheng3660]

Center is 6.5 ox’ = 1.188MPA , oy’ = 11.81 MPA

[@tturi2]

I just took 8ksi as 8mpa just to learn the content, I'll worry about metric vs standard when i need to

[@arlow5497]

24:04 center is at 6.5. everything makes sense now 🤘 . I get how we find the rotation angles and what my Prof called the 'beta' angle.

[@ntuthukoncatayi3593]

was also confused for a minute until I looked at the comments to see if someone picked that up.

[@kimtaetae3882]

Yeah i also notice the center is wrong

[@scottdonnachie8442]

Got me too there. Glad I checked comments

[@arlow5497]

Exams tomorrow and just finished the practice problems. Dr. Hanson coming in clutch!

[@TomasEnriqueSierra]

I feel like a class nerd again when replying super fast to Profesor Hanson's questions! Thanks!

[@updownleftrightish]

I’m gonna buy the book for the years of help you have given best lecturer out there

[@tturi2]

i owe you my solid mechanics qualification thank you

[@manuboker1]

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

[@socalicomm]

Wasted a lot of time listening to another prof trying to teach this. Now 11 years later, I am pretty sure I can do it every time.

[@terrancepage9163]

Am I the only one not sold on the circle method? I feel like I would mess that up on a test lol

[@stephenadjei8413]

Center is at 6.5 for the last example.

[@dineeshak.6254]

evry time i havave a question i just comee to his videos.... great explantion sirr

[@AbdeenzRock]

at 27:00 how did we decide that tao is positive?

[@diegonunez2691]

Jeff Hanson more like jeff Handsome 😍

[@charliemacphee7614]

the man. Thanks jeff.

[@sandeepsingh4042]

BAMMM you are simply awesome.. Respect..

[@rjsathya9949]

jeff you great man

[@rodrigocamara26]

Thank you sir!!!!

[@tumelothatedit3484]

I need help why is the rotation angle 30 ? 60? etc rotation is my problem.

[@sahibhara7611]

i believe in mohrs circle angles are different. If the angle change is given in the problem, it will be double in Mohr's Circle because theta = 2theta in mohrs circle. so you just multiply the "outside world" angle by 2 to get it into the "Mohr's Circle World"

[@sandeepsingh4042]

in some books y face is rotated could you please explain why is it so?

[@GhuzaRegiNaufalPrantoko]

thank you om jeff

[@kimtaetae3882]

Can someone explain fr the last example how the x' is subtract with 5.31 ? I don't understand the x' but for the y' is got .

[@DRPSET]

The distance of x’ (for the x face) from the origin of the planes is 7.5 minus the base of that triangle we found and that’s why we’re subtracting

[@chafinawel]

you make it really funy to learn thanks

[@H-engineering]

Second stress element I found centre = - 0.5
@Jeff help

[@chamarayt5796]

thankz sir..

[@OceanDreams-xs1ii]

centre is at 6.5

[@kursatper]

Thanks

[@noyn9003]

**Center 6.5 (3rd stress element)

[@ramadilebartholomewmonyake1678]

u saved me😭

[@DarylAyao-ao]

how does-3+2=5????

[@oz30ification]

He's trying to find the center, so the amount of units from -3 to +2 is 5 units away.

[@mawia2402]

i love you
