I'm sure not many people notice it, but there's a ton of editing done here. Impressive

[jaspalsingh-ivvj]

when we hear from headphone, there is always one side of headphone is not working in your try to fix it.

[jobinaugustine]

i think u are confused with the yield stress .u said for ductile material failure point is ultimate stress .

[harimyoldpal]

Nice video but i think max value of stress to be considered for ductile material is the UTS not the yield point(in the video it seems UTS is confused with yield point.Yield point comes below the UTS in stress-strain curve.) and the max value of stress to be considered for brittle material is the yield point.(as it breaks soon after the yield point.)

[subakaranr.]

More importantly this theory can not be used for a Ductile Material, because for a Ductile material the failure criteria is Yielding not UTS and in ductile materials failure can also occur due to shear, but this theory does not say anything about the Shear stress, so It CAN NOT be used for Ductile material

[-avanishah]

I am not doing any tuitions just because of u sir....Thank youuu so much

[viveksavaliya]

sir, why we taked about shear at the end of the lecture and in this thory case is only about compression and tension.then why we used shear for applicability of material ahich is ductile and brittle?

[vat_]

sir thank you for your explanation
I like your videos
they are very useful

[imayankkr]

yield stress is taken as failure criteria for ductile materials..and max stress and yield stress are along different points in stress strain diagram

[nyaikanelson]

Thanks for your videos, am following up. I want to design a machine.

Go to school and teach pupils. 7 min of failure of my life

[rohitbhosle]

Nice information sir ty...but maximum stress should be ultimate stress not yield stress I think so. ..btw because u of interest in som is generated inside me

[kahkashanperween]

Sir... This video is soundless infact your some videos have no sound and I could not learn from this ... plz try to solve this issue 🙏

[ahmedsaad-hjey]

is it so simple? why i didnt see mohr circle with ur analysis? is it enough to just consider the stress in one dimension?

[mdtauseefraza]

Your teaching medhod good that's great I like too much your teaching style

[sumanmanna]

Sir maximum stress is not yield stress in ductile material. That is sir mistake in basics. If material is beyond stress stain proportionality limit it is at its yield strength.

[lokeshgurjar]

sir please solve the queries of those below viewers for better understood of new viewers.

[jacobbelmontes]

Little confusing, Point A is the proportional limit, just above Point A before Point B is the yield stress, and point D is the ultimate stress or more commonly known as ultimate tensile stress. However, in this video he keeps calling the ultimate tensile stress the yield stress and it is wrong. My machine Design book by Norton, even states that it is Sut which stands for Sigma Ultimate Tensile. This guy needs to stop calling it yield as he does in all his videos

[ManojKumar-mhpm]

A sir small error you swapped yield and ultimate stress.
