6. Principal Stresses and Stress Invariant

[@ritimech2832]

Sir why don't you complete the whole syllabus ☹️u re such an excellent teacher.....my college professors haven't taught a single chapter.....your videos are the best on you tube and that is my only source of studying advanced mechanics of solid. This subject is in my upcoming semester.....m so much worried how will I complete the subject

[@shubhamsaurabh8353]

Come back

[@supunmalinthasandanayaka885]

Thank you very much sir for your simple explanation!

[@shubhendrakumar8077]

Hello Sir,
Sir I need the complete series of Solid Mechanics that you made please let me know the procedure.
Thank you

Hi
I am in the process of making more videos. I was occupied with some work in our institute and couldn't. In coming days I will be posting videos here

[@nabinbista4213]

it was great explanation . thank you sir it made my concepts strong

[@chetan9gaonkar]

Thanks

[@tabzz03]

Excellent explanation ❤

[@marxregis]

Excellent video sir

[@07samratmudi68]

Sir please continue the lectures Sir

[@tolgahancivek1595]

Sir, If we, for example want to have an expression for sigma_1, sigma_2 and sigma_3 separately, what should be the procedure for that ?

[@destamelka1589]

please answer

[@srinivaspeddoori9766]

Great lecture

[@chetan9gaonkar]

Thanks

[@geralddobel1935]

sir! do you have a sample problem for Principal Stress and Stress Invariants?
Thanks!

[@Somalciviltechinsightsf9695]

Superb

[@nakulpampaniya9745]

Thanks a lot

[@chetan9gaonkar]

Thank you

[@memorymaven]

Where are rest of lectures ..i think some of lectures are not uploaded

[@chetan9gaonkar]

Yes. Will be uploading shortly

Sir u told that on principal plane only normal stresses are act so why u compare the resultant stresses in X y z direction to the cauchy stress formulae in cauchy stress formulae there are shear stress also present in the plane plss reply sir

[@chetan9gaonkar]

I am unable to understand your doubt. Please email me your doubt in detail on er.chetangaonkar@gmail

[@bhargavib4946]

Sir, why principal Stresses are said to be orthogonal??

[@chetan9gaonkar]

To correct your question, it is principal planes which are mutually orthogonal. And since principal stress acts normal to principal plane, they also become mutually orthogonal to each other. In my next video I will prove that principal planes are mutually orthogonal.

Thanks sir

[@salmanlaakhani1773]

Sir needs in notes format for end moment revision

[@venkateswararaoj3855]

Thnx bro

[@Lozaba]

sir can you solve some questions for me till 12am?
i shall be very thankful to you .

[@nabinbista4213]

i think sir there is one mistake . .there must be a negative sign ahead of I3

[@chetan9gaonkar]

Kindly give me time stamp if possible
