[@pompytalukdar1761]

from engineering mechanics to here, your videos are too helpful . Keep doing this good work,Sir.

[@NipobithiBagchi]

Dear Sir, at 33:30, if P acts in that direction causing linear elongation, wouldnt the diameter become shorter? the expression being L+del L and d-del d?

[@mdkalimullah4207]

Ur channel deserve more than one million subscriber ❤

[@rishabh3189]

Sir, according to me, for the last part, for volumetric strain of circular rod, if tensile force is acting, d should become d-delta(d). So in final eqn, instead of plus sign, minus sign should be there (Delta(L) /L) -2*(delta(d) /d).

[@ganeshpediredla5338]

Sir really thank u so much ... because of I am continuing my b.tech through part time mode ..Ur videos is helpful to me a lot ...sir my humble request to u plz upload another chapters also in MOS. subject ......tqqqq

[@MrGyana1984]

Sir today I have seen your lectures on Mechanics of Solid, it was awesome. Your way of expression is superb. I am really glad. I have seen lots of lecturers from Top institutes Like IIT those are nothing as compare to yours. I am a big fan of yours.

[@kishore2486]

True

[@kritarthtripathi7157]

I watched the previous lectures sir and your way of teaching is definitely amazing. I am learning without any doubts for now, I hope your lectures can help me score good in this subject which I am only afraid of right now in my 3rd sem diploma,..... Thanku sir 😊

[@mdkalimullah4207]

Ur handwriting is outstanding. Big fan of u.

Mindblowing Videos SIr

[@mwaleed2082]

Sir , may I have your permission to make the exact same lectures in hindi? These are so good.

[@Farzie_engineer]

Hello sir ,in last case of circular bar due the linear strain the length of bar which is L will increase to L+∆l. so due to this... Don't you think if the length increases diameter will decrease.and it will become (d-∆d) form d..as I learn from your vedio this term will not affect on the equation because it is very small and negligible...I am not pointing out your mistake may be this won't be a mistake..and I dint take it in right way . ....this is just a dout in mind mind....

[@sathishsathish6811]

Yeah! Same doubt I have. So final ev value is linear strain in the direction x - 2e diametrical strain

[@abhisheksukka4]

Sir in volumetric strain in circular bar when length of the bar increases then will diameter decrease or increase in order to maintain volume constant.

[@mdkalimullah4207]

Congratulations(belated) Sir aapke channel ko silver button mila. Kal Mera data khtm hogya tha.💕💕💕💕❤❤

[@ManasPatnaikofficial]

Thanks Kalim.... Stay blessed ☺👼 brother...... Do join me via Facebook as well.

[@shaireenwaheed6492]

Sir When there is change in length (l) there must be change in diameter if length inc. Then d is going to dec. So why add Delta d to it. It suppose to be dec.

[@kirankumarboyapati5065]

Thank you so much, SIR.

[@abinashmahakud448]

!!!!!!!!!!!!!!! In biaxial loading condition , will we get only one Youngs Modulus or 2 Youngs Modules as per x and y direction ?

[@kritarthtripathi7157]

Sir.... Due to tensile stress, the diameter of cylindrical bar will decrease so, why you used /\L + L??

[@ayushpriyadarshi9897]

Entire lecture is awesome mannner ...but a mistake ..for circular bar ...when applied tensile load then diameter will be decreased....and length of the bar is increased with delta l....👍🏻🙏🏻

[@bkumar7380]

i am also think this

[@narendrakumarbn8819]

Sir for the volumetric strain of cylinder bar the final formula is wrong I think.. It should come Volumetric strain = strain in length - twice the strain of diameter This formula is given in R K BANSAL book

[@kishoreb8030]

Sir, one doubt, in Volumetric strain for Circular bar, the diameter decreases so the eqn should be d - delta d and so on in the final eqn also..

[@raguravi1659]

just Assume, You need not write it in the equation (since he is just writing the raw equation and saying that the value changes and not increases), when solving the values the del value will automatically be considered with the minus in before it.

[@miteshsindhav]

Sir how to solve this question The front view of a line AB , 90mm long measures 65 mm . Front view is inclined to xy line by 45° .point A is 20mm below hp and on vp. point B is in third quadrant . Draw the projection s and find inclinations of line with h.p and v.p .

Sir...how do you solve this problem...plss help me... The point A of a line AB is in HP and 60 mm in VP. The point B is in VP and 40mm in HP. Distance between the projector is 70mm. Draw the projection,true length,inclinationan and traces....plsss post this as fast as possible before 2nd of Jan 2k19

Sir you should make pdf notes and upload them as well

Pls don't be such a lazy bag. Actually writing the notes ourselves helps our brain grasp the sub even more effectively. So do take notes instead get them photocopied.

Dear Manas, On couple of occasions your coordinate axes were not right handed. I would have not commented but then I was forced to because of high standard which you have created for yourself.🦁

[@ManasPatnaikofficial]

That's a mistake on my part. Glad you pointed out. Will stick to the Right hand coordinate system in future.
