Virtual Work Method Lec 4|| (Problem 2)|Engineering Mechanics|First Year Course

[@ashishpurohit9138]

Correction......At time 2.27 second: In value [ K* delta], delta will be L Cos(theta) instead of L Sin(theta)

[@PankajHoodaBME]

yeah,it was creating a doubt .

[@sverma1178]

you r right bro i have same query

[@88NA]

yes Lsin60

[@dineshms7667]

Yes

[@s.t.s.hasantha7416]

Thank you. I finally understood virtual work because of you.🤩

[@yashgarg8382]

Sir you are awesome mechanics teacher

[@Mahadeva...]

delta is L COS(@) and not L SIN(@)

[@ashishpurohit9138]

Yes it is an error..It is already there in my comment..plz. COrrect cos instead of sin

[@onsirclasses3083]

Yes u are right

[@KetPingChong-mu3zx]

Got a question regarding the sleeve: when the bar AB is in a fixed position, why doesn’t the sleeve slide down? Gravity is pulling it down and there’s no support in the vertical direction.

[@darshanbendre558]

Very Nicely explained... thanks sir

[@ashishpurohit9138]

Most welcome

[@consistent2025]

Great video 😊

[@فهدالعجميي-ر3ل]

Keep going man thanks😍

[@ashishpurohit9138]

Thank you

[@kanakkotriwar6148]

At 18:10 dell = Lcos(theta) and not Lsin(theta)

[@ashishpurohit9138]

Yes Dear It is written wrongly, the same is there at 2.27Sec. Thank you for identifying it. Please make suitable correction in your solution.

[@subhmaz3284]

Sir correct value of k after solving will be 72.168N per m

[@88NA]

this video is helpful

[@princerajsingh2792]

I have a question which I want to ask with you please provide the medium through which I send problem

[@matthewzarate9116]

Thank you

[@rajbastakoti5012]

thankyou sir

[@tusharabbott]

shoulndt be delta=Lcos(theta)

[@ashishpurohit9138]

Yes, its a mistake, in the spring force calculation. In k*delta the value of delta should be cos component of the length of the rod. Thank you for indicating error.

[@owenahereza3181]

Explanation you wont find anywhere else

[@srider9781]

we can directly do by balancing torque, don't know why we use this stupid method

[@senpaidawwwggg]

but in examination , if its written solve this use virtual work method , then???

[@A.Hisham86]

del L eqauls L cos theta, and not sin theta! check that! the result is false.

[@Pragya-fp2gj]

you teach worse than my professor
