it do be like that.
That "And we're done" at the end was fitting. Because I now understand this
This video deserves a LOVE button
The best explanation I've ever found. Thank you.
Thanks so much for your Clear and to the point info. This is the best video to learn Mohr’s Circle I have found!

Is it just me? The video lectures that I really needed are the ones that I find very late.
Thank you for this wonderful video! Exam is tomorrow! Mohr's circle, combined loadings, beam deflections etc... wish me luck ! ! !

I REALLY needed this. Our books explain this very poorly and this video makes it all clear! Thanks
It was an awesome video, no way my college teacher taught this way. U r Excellent. May God bless u.
Perfect explanation!
This was an amazing explaination. Thank you!
Very clear explanation! Thanks!
Wow...fantastic explanation
excellent stuff, got an exam in 20 min and I literally only understood what all this was now. Thank you.

Great, thanks
Love ya!
Very good explanation
superb..
Thank you
thank you
In problems how to know which max shear stress is given? Like is it the circle between xy or xz or zy or the absolute
Thanks for the video
There is no escaping reason; no denying purpose. Because as we both know, without purpose, we would not exist.
superb lecture
no words sir thanque sir
Really a great video😍

Lovely Explanation. One Question: @9:48 Shouldn't Sigma_1 be equal to 25 and Sigma_2 be equal to 50? Sigma_1 is the Principal Stress on X Face, which is given as 25. As I see it, if Sigma_Y > Sigma_X then the circle gets horizontally flipped compared to the initial circle you explained, doesn't this alter the way the readings are taken?

You have a good point. However, by definition, Sigma_1 is always the most positive of the principal stresses (always on the right side of Mohr's circle) and Sigma_2 is always the least positive of the principal stresses (always on the left side of Mohr's circle).
Isn't the shear stress for sigma y positive because its going clockwise and negative for sigma x because its going ccw?
I devote my final exam to you
Great
GOD BLESS!

Where can we find the mathematical deduction of the formulas for the mohr's circle in 3D?

My book is so bad at explaining how to do triaxial stress problems.
But the plane stress condition is defined as no stress in perpendicular planes like Touxz, touyz both must be zero....
I would give you 2 likes if I could....this helped a ton! Thank you.
hiii what if the given is tau x, tau y, and tau z, how can i get the value of tau xy, tau yz, tau xz? thank youuu
How to derive stress transformation formulae using Mohr's circle? I mean how to geometrically interpret the stress transformation equations from the Mohr's circle
I didn't get why you plot tau down axis ? could you explain it >
@introductoryengineeringmec9114

You have the option to plot tau positive down or positive up. If you plot tau positive down, then angle directions on Mohr's circle match reality (clockwise angles on Mohr's circle = clockwise angles in reality). If you plot tau positive up, then angle directions on Mohr's circle are the opposite of reality (clockwise angles on Mohr's circle = counter-clockwise angles in reality).
So I tried plotting my circles using the planes as you did but I have a shear stress to consider and my circles ended up overlapping each other which I don’t think they’re supposed to do. Is there another way to plot it? SigX = 100 SigY = 40 SigZ = -60 TauXY = 30 TauYZ=TauXZ=0

You have 3D stress state, which is a little more complicated than what I discuss in this video (plane or 2D stress). Here is a link you could try: kzread.info/dash/bejne/eYKkkqx6ZLKTlso.html

You did not mentioned what are the subscribe letters s and p in the angles. I think P is for planar and S is for shear?
@introductoryengineeringmec9114

You are correct, the subscript "S" is for "shear", but the subscript "P" is for "principal".

I dont see any compressive stress in the assumed stress element. Please be more clear and concise in what you explain conceptually.
@tomaszniemy6066

And I can see plenty of compressive stress. It's between sigma2 principal stress and 0. One just needs to "cut through" the element (or the point, to be precise) with a line (2D case, plane stress) in a certain way. Don't try to understand lesson 2 before you understood lesson 1. I can't see "stress element" you mentioned . I can see an element (or rather a point) under stress, though.

This vedio is conceptually zero. No concept nothing, just given formulas. Sign conventions are also totally wrong.

What about making a proper "vedio" yourself? We have a name in Poland for people like you. It translates into Inglish as "ungrateful bustard", or somethin' like dat. No regards
