Woah! Theory of Failure is this simple? Damn it I never understood it in my engineering! I always skipped this topic for my semester exams!! The way you explain is so awesome! Am very lucky !
Thanks a lot. There is no source where theories of Failures explained deeply like you taught. Sir you have cleared all my doubts regarding this topic. Thanks a lot from depth of my heart and keep it up sir..
one of best educators in mechanical discipline now a days...
Yes he is
The Best teaching on theory of failure
Thank you very much Sir for the concept. 🔥 Finally I understand it clearly
Nice video 👍👍! As a fellow TH-camr, I am on the lookout for fresh ideas! Nice Job!
At 37:30 The safety condition and failure condition have small error. it will be a safe load in less than or equal to yield stress and fail if greater than yield stress.
amazing presentation skills sir!! reflects your teaching
experience and depth of knowledge in concepts understanding
Thankyou sir for a pure and clear concepts.Now my stresses get reduce✌🥰
You teach very conceptually....your teaching way is awesome 👍
All the highest rankers...in gate are knowledgeable..
Sir...the way u explaining is fab
finally i understood this topic...thanks sir.
Wow.....what a lecture...
Great job!
Sir, xy graph : due to stress only, strain occured. Y - dependent variable and x - independent variable But in graph stress in x axis and strain in y axis . What is the reason of the stress - strain graph
@@Yash.027 11:36 , sir
@@Yash.027 thanks sir
@@Yash.027 tq sir i have cleared my doubt but sir why only x axis we take strain and y axis as stress?
@@vamsisrikanthrallabandi7015 its nothing but x as independent variable and y as dependent variable...and we can relate strain as a function of stress...
Plz correct me if i m wrong..i ll be pleased
Finally I understood the theories
Sir in Principal stress or Rankine Theory We need to use Principal Tensile stress or Principal Compressive stress ??
Hello Sir! But here you have considered all the failure points with reference to tensile test. Y not compression test?
Great lecture..
Good please continue sir
In max pricipal strain theory , why the 3rd strain component is zero in 2d loading ? 49:08
btw very lucid explanation...
thanks
Your question has the answer. Only 2-D loading
Slip of pen. Only sigma 3 will be zero. Strain will exist in that direction.
At what condition sigma2 is > sigma 1 ?
Sir, I want to buy your course, but I have a doubt that your video course of one year is for one full year or till gate, for example , as I am going to 3rd year of b.tech and if I buy your video course and other course in July 2020, then will it be upto July 2021 or till gate exam?
Please clear the doubt Sir.
1 year video course will be valid for 12 months from the date of enrollment. For further queries, feel free to call us on 9536651816 or mail at support@exergic.in
@@ExergicGATE thanks a lot Sir,
Principle of stress and strain video request sir
Does your course cover the complete syllabus for gate?
Sir is there any discount on paid video lectures?
Pls visit our website www.exergic.in or call us on 9536651816 to get any such details.
You are the best.
"Theory of Failure," I thought it is a motivational video so I clicked on it but here is something different.
boz ur not mechanical engineer
Ha ha
Bro it's not motivational video
This is Our Civil Engineering chapter.One of the most conceptual chapters.Questions coming from this
@@SidharthMishra99 Thanks.
@@SidharthMishra99 and also for mech students. But it is a motivation video itself bcoz of the clear concepts.
@@arnabbhattacharya7772 Yes,that also true
Sir in Tresca Theory in 2d, putting sigma 3 as zero could lead to sigma 1/2 or sigma2/2 also not always difference of two??... Plzz clarify
Yes, then take maximum magnitude among these three
Sir when 'Solve Combo' coming for GATE 2021 ?
Solve Combo is there already.
Details here: exergic.in/combo-packs/
There is an error at 48:00 in the sign should be less than or equal to instead of greater than..
1.3 hr video 😮🙏
A helical spring is produced by cold winding a wire around a cylindrical mandrel. The wire has a square cross section 3 x3 mm and the coil mean diameter = 30 mm, wire material is assumed to be elastic-perfectly plastic having Y= 60 kp/mm², S= 2 x 10¹ kp/mm². taking elastic recovery into consideration determine the diameter of the mandrel which gives the specified coil diameter .
Can anyone please find me the answer to this
In rankins theory we can never take sigma 2 as major principal stress is sigma 1 and that will always be greater , somebody please explain?
Go through the formula of Sigma 1, 2
Sir if principle stress is equal to yielld stress then failure ocuure or not. Bcz acc to yuou failure occure but acc to book of Ss Rattan in this condition failure not occur
@ 01:16:26 why sigma v is taken why not sigma v1 , sigma v2 , and sigma v3
@@Yash.027 nicely explained sir, keep bringing these type of videos, really helpful.
Is this video is sufficient for GATE CIVIL ENGINEERING
In distortion energy theory Why the stress responsible for Change in Volume is same , it can also be different like stress component for change in shape are different. Why the stress responsible for Change in Volume are not different ??
Why all the volumetric stresses are same on last theory (distortion energy theory)
sir please upload crase course in youtube
Woahh
Sir, you have missed the explanation of third theory
It is there in the next part of the video.
@@ExergicGATE Please upload 2nd part
Sir pls upload one video on merchant circle
Whether exergic is available for ece branch
1:09:00 why is sigma v same in all directions ??
From where we get second part
It's not easily visible on the board
Sir. Is this video different from course video on theory of machine which i am going to buy.
Whatever videos we upload on TH-cam are from EXERGIC Video Course only.
For any further queries you can call us on 9536651816 or mail at support@exergic.in
Nice sir
Thank u .
Thanks
Thanks sir
Maximum shear stress theory is not discussed here.
It is discussed in Part-2
Make sure to watch both.
Can I purchase subjectwise videos separately????
Yes you can. For details, visit : exergic.in/gate-video-course/
Magic boy
Sir please release mohr circle session
❤❤❤
Plz let us know the actual reason for the shape of Region of Safety.
Will be discussed in Part-2 of the video.
When will the Part-2 will be uploaded? Waiting eagerly for that.
Part-2 is LIVE now.
Last theory of failure is I'm don't understand
Sir second video kab aayega??
Part-2 is LIVE
Can you please post a video on Iron carbide diagram and heat treatment.
If any one required the same pls like this..
