Why Mohr's Circle - Brain Waves.avi

[@shaileshjoshi7912]

Only video which explains why instead of how. Thank you very much!! Was looking for an answer since ages.

[@sushkoli8034]

teachers like you are pure gold.. :)

[@SonyaG3]

Too often, Professors delve into the trees (and branches) without showing the forest and students do not understand why they are doing what they are doing. Thanks, you are the first instructor I have seen relate the micro of the Mohr's circle to the macro of the real world (using your compound bow example). Thank You.

[@targeturattitude]

I"ve been searching for Mohr Circle for about 2 days extensively and you are the one who showed me the true meaning of it. Thanks a ton for that magnificent depiction.

[@sterlingsmith361]

I have a BSME and have passed the FE, I take the PE in TWO days. Because of this video I now understand what the point is THANK YOU!!!!

[@vaggs75]

You are the only person on the internet who can actually explain this. Thank you. I thought I was stupid, but it turns out everybody is just pretending to understand.

[@ErkulKurulay]

You are so much helpful with "anchoring" the floating knowledge we have in our minds. Thank you.

[@purdueMET]

You're most welcome :-)

[@oguzoktay79]

One of the greatest professors I have ever met, wish I was your student during my undergraduate.

[@Titan.Uranus]

Thx for letting me understand and appreciate the underlying fundamentals of the application of mohr's circle. U make it sound more inspiring instead of a neccessity of tedious labouring for a end result!

[@purdueMET]

Thanks, I'm glad you liked it :-)

[@The92gopal]

Thankyou Prof! that's one of the simplest explanations I've ever come across

[@nadermehdawi1981]

Sir, I have always wondered what is the physical meaning of Mohr Circle, YOU have explained it in a very great simple way to understand the physical meaning of a math I do everyday. THANK YOU

[@grahamtomlin2289]

brilliant examples there. I've gained a lot by watching this. Thanks

[@Subbu1811]

Thank you very much, Sir. Your explanation is excellent to comprehend Mohr Circle.

[@kedarzc]

WOW ! You've cleared a doubt that has been existing in my mind for about 5 yrs !!!

[@michaelmorrison5675]

You obviously know your audience. That's critical! Good job purdueMET. I've been a ChemE for nearly 30 yrs. However, my educational background is ME. I'm also a registered engineer. I find your video very helpful. Where I work, we have several young non-tech, sci-fi nerds who ask me aerospace questions. We produce oxidizers for MFGs of solid rock motors. So there is the connection. I find it difficult to explain the physics of rocketry. I get too technical. Your video on "Why Mohr's Circle" is a good vehicle to show them the big picture.

[@zumbatan550]

Thanks for the Mohr's circle video which I didn't really know well and about the direction of the maximum stress.

[@purdueMET]

Glad it was helpful!

[@mustafa1231]

this is an excellent video. thanks for clarifying the concept.

[@massivejester]

Finally! I've been wondering what the hell I'm doing. Thank you! :)

[@tombranley]

this guy is a genius at teaching

[@mayureshbakare3021]

Very good lecture. This is how you start with any type of concept.

[@pedroaraque9997]

Awesome explanation! Just what I was trying to understand. angle meaning and maximum stress. I'd also like to see how they come up with the combined stress equations based on equilibrium

[@moemenmartini3977]

You are the best and l like your systematic way simple and scientific at the same time.

[@hemanthgadhamchetty1523]

superb explanation and good example

[@janoshorvath9430]

Thank you! This 12 mins were really useful!

[@xyz2007123]

I enjoy watching your classes. Thank you!

[@ClaudiaZucco18]

thank you for your videos! amazing teacher, greetings

[@MortazaHussein]

brilliant, you are really a good teacher, i have learnt alot from you. Thank you

[@subramanianchithambaram5779]

you are my favourite teacher

[@sreeragsr878]

You must be my teacher sir.. love you 🥰

[@thecatalystlife]

Sir, you explained it the best. Thank you.

[@vorsprung04]

Great explanation. Would be nice if you follow this up with a real worked out example. Thanks

[@andrekuma]

Thank you Sir, i wonder this question for long time ago.

[@ashishtiwari1912]

Your videos are too good..do you have a video series on FEA? thanx :)

[@RK-tr7wo]

Great explanation of WHY professor!! Would you be able to add some video explaining how to not overkill design by using excessive safety factor? I mean how much min. Sf should be used for a design?

[@starling100]

Fabulous explanation!

[@alberteinstein6992]

Great explanation

[@purdueMET]

That's very kind of you. Thanks - RMF

[@joseemanuelrangelescalante7375]

great , i would like to know how to interprete the angle i get with the morhr circle, because is a 2d problem , specificallythe axes of reference ? thanks

[@aleksandrsnaumovs4277]

Excellent video! Thank you!

[@abdullahabduessamad8269]

Lol, I like the way you explain the stuff.... 👍

[@danieltrigo2928]

excelent explanation!!! thank you very much!!

[@nadeemchaudhary6579]

Thanks, much appreciated.

[@aleksandrsnaumovs5166]

Yes! I finally got it:) Thank you so much!

[@MarkoLubonic]

fantastic explanation. Thank you!

[@dantecastillodelasfuentes1026]

But what does the angle exactly tells me? That if I change the direction angle of the rocket it will fail? Or what?

[@pradeepkarna]

GOOD SIR...

[@rajithodlme]

hello sir, why are we interested in finding the stress (max shear/principle stresses) which are not really happening on the element. ie; why r we finding the stresses which wud occur only if we rotate the element ?? because the element is not getting rotated in physical world, so why r we interested in that.

[@sarahmakarem3034]

that was really helpful, thank you so much

[@diablodb3626]

i didnt want to start the video but m glad i did...thanks :)

[@purdueMET]

It's like tearing off a bandage, huh? I'm glad you decided to watch :-)

[@sujitjoshi7170]

You sir are awesome.

[@SN1350]

Hey you professors at OU, watch this video and learn a thing or two about teaching. Your students will thank you for it.

[@purdueMET]

@kaizerwilly You bet. I'm always looking for new topics.

[@karanchowdhary5969]

Nice teacher

[@pradeepkarna]

SIR CAN U GIVE A CLEAR CONCEPT FOR WHY WE NEED BENDING STRESS AND SHEAR FORCE?

[@tmtan1303]

+pradeep karna Beam will fail by bending stress mostly among the others stresses

[@danpt2000]

if you look at many of the beam problems in Structural Statics course, a vertical load in beams will cause bending moments, and shear loads in the beams. Thus we need something to take into account a combined Bending and Shear stress.

[@tomasenrique]

My god, I love you. Like not in a creepy way, lol.

[@herrasnelmann]

The title should be: 'Rocket science explained in 12 minutes'

[@nataliechan6779]

thx, i am dealing with it in fatigue analysis, it's really helps

[@ahmedhendy2489]

sorry could you tell me how y use it in fatigue ? [e-mail]

[@michaelchristain6218]

Excellent!

[@emptycl0ud9]

Isn't that a mathews conquest compound bow

[@imstudentxxxxx]

nice video!!!

[@iKs4uLeagueOfLegend]

can you teach at our institute

[@trexinvert]

You skipped the part(if we didn't have Mohrs circle) where engineers would stick 180 strain gages(1 for each degree of orientation) onto the rocket to find the maximum stresses.

[@peterkizer6163]

Even with Mohr's Circle, and high speed computers, there is still a lot of testing of physical objects.

[@ChrisTheDIYguy]

you are my hero

[@ansariyaseer4651]

thanks sir

[@jonathantheriault7229]

Finally I understand

[@burakceylan9409]

OLM ADAMIN DİBİSİN VARYA

[@emrage]

Translation 'You da man!'

[@265HITMAN265]

nice jacket sir

[@DanPaulCookson]

Nice explanation, but please learn how to pronounce 'poisson', hearing 'poi-sahn' is rather grating
