what if tangential acceleration was there at q?
thank u sir..
from this video my basic concept is clear..

sir acceleration diagram is by considering the relative acceleration value right which is in rad/sec^2 but here u have considered velocity value which is in m/sec
Good work sir. Excellent explaination

How do you know the true acceleration or the tangential acceleration of QR and RS is to the left but not to the right?
Henda the two tangential components will cut at a point which is possible only on left side. Not right side
Got my exam tomorrow, just started studying.. lol.
This was super helpful, Thank you!
Abbas Haidari all the best for your exam
Me too 😙😂

Sir I have one doubt if crank is rotating in clockwise direction the while drawing in which direction we have to draw the vectors on acceleration diagram
Like for example if crank is rotated in clockwise direction then it's radial acceleration parallel that I know but in which direction we have to draw it's tangential acceleration -left or right
Aditya Mohanty both directions...the direction in which it intersect has to be considered...
Very very very useful sir.......
mohamed irsath thank you
Thank you
Sir but since angular velocity is constant for link pq it should be constant for qr also .so why we are drawing tangential component for link qr it will be zero only naa?? Sir plzz clear
Aditya Mohanty in pq normally a motor attached to create rotary motion since the motor rotates at constant speed ,here velocity is constant. At qr there is no motor
Oohokk sir I got it so the conclusion is that when angular velocity changes the linear velocity of the point on that link changes due to which tangential acceleration also changes .am I right sir??
Aditya Mohanty yes
19:25 how you say alpha direction is CCW please clarify
Because angular velocity omega is clickwise
Tnq sir
Hi i dont understand why a radial acceleration is not zero too for constant angular velocity...pls help
Radial acceleration = radius x change in velocity.
If velocity is constant then change in velocity is zero. So radial acceleration is zero
its cause velocity isnt contant all long the link ?
@@ilhamh1596 linear velocity is constant since it is rigidlink
Clear explanation sir..tq

Overall it is nice...
Introduction part is very good...
Please explain these points 1) Directions ie....CW and CCW
2) Directions ie. why you taken radial component of PQ downwards..?
These things can help the viewers a lot
Best wishes....
sure. i will explain in my next video.
Regarding the second question, the radial component of PQ will be downward or upward.you can take both direction . the point is on which direction it intersect with other line. If you change the direction also ,you will get same answer i mean shape of the diagram may be different but same size only. in the classroom,we ask one batch to follow one direction and another batch willbe asked to follow other direction. on both direction , you will get same answer.
Good.....
This is the part where many teachers skip.
Your students are lucky to get a teacher like you.
All the best...!!!

initially in the diagram it is shown radial component of acceleration of PQ towards the centre P, but while you drew the actual one it is shown directed away from centre P?Got that confusion for a long time.Thanks
Abhishek P G you can take any direction. The magnitude will not change only the shape will change. Check my video on clarification in velocity acceleration diagram
@@icgindia2970 I was having the thought that the directions were important..... But then when I went through your comment once again... Yeah it is all about finding the magnitude.Thanks a lot.

sir, i didnt get how QR andRS cut over there
aditya Sreevatsa at 17.07 sec in timeline , you can see that cutting point. Is it clear? Otherwise you have to mention the place in timeline where you have doubt.
why 17.07 sec?
aditya Sreevatsa in that video see at 17.07 sec to see tangential components
aditya Sreevatsa I cant understand your question. Ask your question more clear ly so that I can answer.
Are u asking about clockwise anticlock wise direction of tangential component?
I am not able to understand where does the tangential component cut, I didn't understand how tangential component of RQ intersected with RS
sir teach angularation diagram in accelerations in mechanisms example 8.5 8.6 8.7 8.8 8.9 sums

ENTERTAINING KENDRA no hindi...only english...I am from tamilnadu
@@icgindia2970 so what you are also indian and our national language is hindi. I couldn't understand english so much well so i told you. Otherwise as your wish.
@@ChandanKumar-xb6hy LOL stop
Our paperwork is officially either in English, Hindi or some other language
In most of the schools official language is English, so better gear up now!
@@ChandanKumar-xb6hy 😂learn English
dear dr ...nice explanation
may i have your email please?
