Thank you for the video sir. it is really helpful and informative. Question I was asked in the interview - at 22:00 in vide, what happens to the material when we stop applying force in between point C (lower yield point) and point D (ultimate stress point)??? What will be the physical effects?? When again we start putting same amount of force on that material, how will the curve behave?
56:26 proof stress concept is used for ductile or brittle? Because we can't find yield point elastic point easily in brittle. So we should use it in brittle only right. But sir says it is for ductile only?
Sir, in case of compressive loading, true stress will be lower than engineering stess. So, in this , can't we say true stress strain curve is giving more reliable information ?
But if we use actual area instead of instantaneous area, stress value increases otherwise stress will reduce. That is not correct know. I think engineering stress strain is correct for compressive also
Sir plz... plz... plz... make a video on effect of temperature on stress strain curve & how the curve will be of same material for different temperatures...
Sir aapnai mild steel and cast iron ka comparison curve batya usmai ek slide mai cast iron mild steel kai graph sai nichai ha but in other diagram cast iron is above the mild steel which one is correct?? sir plz reply
Why are there giant holes in the pipe going from the regulator and control valve to the burner on my LP gas cooktop? How does the propane not leak out right there?
sir i have one question , why material fail at fracture point although it is lower than ultimate stress ?? kai par muje iska convincing asnwer nai mila , please guide
sir,load is removed when point is located between upper yield point and lower yield point....what happened of behavior of material..........question asked in barc
The only video which can explain the concept at its best level...no other can explain the way sir explains...you wont have a doubts after this
Sir, modulus of elasticity is 210 GPa not Mpa. Video at 43:32
I haven't this much of information anywhere else 🙏❤️
best ever explanation I have seen so far
Thanks for the video
Please make vdo on unit conversion also your vdo is full of knowledge concepts trick everything great really
Very good explanation sir, about basic concept of stress vs strain diagram
Alot of thank my dear respected sir for providing best interview purpose session
Thank you sir...
Sir please continue 50 most important topics in gate
what a depth explanation . about this topic, 👍 👍 greatt sir
Thanks For Your Effort for Free Teaching Thanks Sirji

there will be a permanent deformation and we need to apply more force to again elongate is m right ?
Great work you are doing an excellent job.
Now my all doubt regarding Stress strain diagram is cleared...😄
Only video on TH-cam which describes this very important topic in detail..... Thanks thanks thanks thanks thanks a lot sir ji
Sir aap bahot acchese padhate ho,plz machine design and Tom ka bhe lecture le lo na
Thank u so much sir.. 💯💯💯💯💯💯💯
That is appreciable sir ... nicely explained but at 49:00 you mistakenly said rubber is ductile material but it's brittle.
Nice lecture sir
good for interview preparation
All doubts all cleared

his every line solve big mcq problem
1. True stress is more than engineering stress and true strain is less than engineering strain.
Lot of thanks sir
Sir plz... plz... plz... make a video on effect of temperature on stress strain curve & how the curve will be of same material for different temperatures...
what a class.. from cuet.
Increase in stress level after lower yeild point is because of strain hardening
Sir plz make a detail video on kyoto protocol
Thankyou Sir❤️
Good
Note: sudden fall at yeild point is because of the presence of cottrell atmosphere.
SIr please make a video on plane strss and plane strain..It is very difficult to understnd plaine strain
Thank you Sir
Sir what is secant modules of elasticity
Thank you sir...
Sir how som is important for civil engineering?? Make a video sir please

Why UTM is called universal testing machine?
Thanku sir

thanx sir
Sir how som subject is useful for civil engineers?? Video please
sir,load is removed when point is located between upper yield point and lower yield point....what happened of behavior of material..........question asked in barc
It doesn't get permanently deformed,it regains its original shape
Thank you sir, plz could you explain how we can calculate the instantaneous area experimentally?
By using strain gauges and little bit geometrical calculations
thnk u sir
sir where is the pdf of this lecture?
Dear Pdf kaha milega
Sir, can we know about Poisson's ratio from stress-strain diagram?
sir please teach in english
Thank u sir..
Thanks sir
