we do not demand u for anything because u have contributed sssoooo much for students irrespective of ur routine .... so thank u so much and may god bless u good sirr
sir please help us in refraction through a plane surface glass prism and all the partt please sir upload a video of this chapter also i am waitingg pleasee sir...
Sir you have explained us in a very good way... but sir the part of combination of pulleys is not explained in any of the videos made on the topic of pulleys. Sir, it is my humble request to you to put a new video on the above explanation of the combination of pulleys 😊
Thank you Sir for the explaination But i our School we are told to make the strands completely straight and also in some books so is it wrong to make the strands a bit rounded
sir plz plz plz plz apse request hai ki ap icse ke maths ke chapters ke concept bhi explain karna suru kar dejiye.... maths toda jaada tough lag raha hai... plz sir atleast toda sa har chapter ka concept bata dijiye.... apka video mai regular dekhta hun.... THANKS IN ADVANCE
Please please please please please please Alakh sir please reply I am a big fan alakh sir please tell that can we consider the tension force and the load as an action and reaction wherr load provides the action and tension is the reaction?
Sir baaki sab samajh mai aa gya bs ek question hai ki rope toh hum ek hi use kr rahe hai na toh no. of strings zyada kyon??? Thank you for your help sir.Keep going.

I think sir you are the best physics teacher on UA-cam for class X ..... THANK YOU FOR SUPPORTING THE STUDENTS CONTINUOUSLY ..🙏🙏
Best teacher of physics and chemistry 👍👍👍
Super teacher
May God give u the prize of ur efforts
Super unique
another very good explanation sir..really got the concept clearly..thank you sir
I'm from previous 2 months trying to understand pulley,but sir by hearing you its looks very easy
Your videos helped me a lot in this pandemic sir
well explained sir thank you very much
With his guidance I got 38/40 in chem alakh sir u r gem 💎 No teacher is like uh we respect u alot😭💝
Thia is physics class how would che come in block and tackle system RIP PHUSICS🤭🤭🤭
How can you increase the efficiency of the block and tackle system of pulleys
Thankkkk youuuu soooo sooo muchhj sir....plzzz do anything for 2018 BOARDS....OK
He has done everything
Potterhead??
Sir bahut lamba wait krwa diya par sir bahut ahche se samjh main aaya
Thank u so much..
Sir please explain on how to calculate the distance travelled by load and effort
Hello ...
I think my answer can help you
Mechanical Advantage = Effort Arm ÷ Load Arm
This formula is given in my book 📚
It M.A is equal to Distance travelled by effort upon distance travelled by load
@@garvmathur4496 bruh you answered her after 2 years she would have passed class 12th by now 😂😂
Sir can we conclude that in ideal case, M.A is equal to V.R ?
Yes
yess
Thanks
sir please help us in refraction through a plane surface glass prism and all the partt please sir upload a video of this chapter also i am waitingg pleasee sir...
Next video is on critical angle , total internal reflection and ray diagrams for prism. Will be there on channel within next 2 hrs
@@PhysicsWallah Sir kya speed h aapki student ne demand ki aur 2hr m video 👍🙏👍🙏
ur videos are really easy to understand
Sir app ek no ki video bnateho... For 10 icse ki to bhut acchi h 😁😀😀
All the best everyone ! 👍🏻
How do we know that a BT system of 5 pulleys must be divided like 3 : 2 ? or for any number ?
Because the pulleys below can not exceed the pulleys above
Savage Ishan
Kitni video dekhi. But aapka koi jawaab nahi ❤️❤️❤️❤️❤️❤️
Sir you have explained us in a very good way... but sir the part of combination of pulleys is not explained in any of the videos made on the topic of pulleys. Sir, it is my humble request to you to put a new video on the above explanation of the combination of pulleys 😊
Really your lecture make my fear out from pulley
Outstanding explanation 🙏🙏
Thank you sir because of you my all douts are clear
After 1 hour I have exam
Mera bhi
Thank you Sir for the explaination
But i our School we are told to make the strands completely straight and also in some books so is it wrong to make the strands a bit rounded
Can u pLs explain why the VR is always equal to the no. Of pulleys without MA and efficiency
sir upar jaada pulleys kyu hoti hai
sir plz plz plz plz apse request hai ki ap icse ke maths ke chapters ke concept bhi explain karna suru kar dejiye.... maths toda jaada tough lag raha hai... plz sir atleast toda sa har chapter ka concept bata dijiye....
apka video mai regular dekhta hun....
THANKS IN ADVANCE
Effect of weight on mechanical advantage and velocity ratio and efficiency
Is there any system (if) where tention on on effort is greater than 1?
Please please please please please please Alakh sir please reply I am a big fan alakh sir please tell that can we consider the tension force and the load as an action and reaction wherr load provides the action and tension is the reaction?
Yes, we absolutely can
Tension ko sab dur rakhte hai bas hmko milti hai😅
😅😅
Better than our school teacher
7 year later the content is fresh 💅💗🌷
I have my coaching exam tomorrow thanks 😸👍
Sir you are the best....
Sir efficiency formula is wrong it's n=workout put upon workinput
Nice video , easier explanation
Where to put tension force
Sir block and tackle system me bina efficiency jane VR Kaise para lagaye plz samjhaiye
Bt system me vr= no of pulleys
In some cases the velocity ratio of 4 pulley system is 5 how come??
Zuzer Zakiuddin when there is 1 pulley in upper block and 3 pulleys in lower block then M.A is 5
@@sneha4869 it can never happen
@@youthkipukar2848 it is not practically possible...but if asked then this will be the answer.
Sir i have seen in my book that if VR=5 then they have made four pulleys instead of 5 why that sir?
Sir ji maja agya kal exam h lekin samajh aya > eficiency =10000% = 100 marks 🎉
Thank you so much sir. You are really great...🙂🙏♥️♥️
I have learnt easily .
Thanks so much sir
Thanks sir clearing all my doubt
Thank you so much sir❤️ understood everything easily 💖 thank you 💗
Is it true that for a block and tackle system,vr =n,ma=n when efficiency is 1 but if efficiency varies ,will values of vr or ma will change
Value of vr is always constant for a given machine
Ik I m late🤣
Sir size of the pulley will be same ....
Can anyone tell me where sir has explained the combination of pulleys
why there are more fixed pulley than movable pulley in a block and tackle system?
Sir is tha best sir in world ❤
If the effort is applied in upward direction then what will be MA?
Super teaching🙏
Thank u so much sir u cleared my all doubts thanks a lot
Really very helpful..thank you sir..
Why fixed pulley must be more or equal to movable pulley??
Very good information sir thank you
Your explanations are justtt awsomee sir👍👍
Very well explained 🖒
Guru ji iska example jo GYM me chest banane ke kaam me aata h usko bhi isi prakar se banaya jaata h kya?🙄🙄🙄🙄
Comments baad me padhna pehle video dekh le.😂
Sir inconvenient direction me kya hota hai
Yeh alakh sir ki first video hai jaha se " HELLO BACHCHO " ki shuruaat Hui thi
- 21 June 2023 04:17
Best teacher
Sir iska matlab no of pulleys is equal to the mechanical advantage plz say sir
Yes but only if effort is acting downward
And there is one exception also
But you can say no of pulley =VR this is correct and with no exception
11:38 sir got a mini heart attack 😅
Sir baaki sab samajh mai aa gya bs ek question hai ki rope toh hum ek hi use kr rahe hai na toh no. of strings zyada kyon???
Thank you for your help sir.Keep going.
its the tension force that we count hope it helps u
It is not asked the no. Of strings
It is asked the number of strands
Thanku
Study matlab physics wala sir
Thank you sir !!
Both definition are right of block and tackle
Sir what if the string is pulled from downward direction
Great sir
thankyou so much sir your explanation is best than anyone 👍👍I can understand very easily 😊
It helped a lot siji❤️
4 pulleys se ma 5 kaise hoga?
Upper 3 aur neeche 2
Sir why we haven't took arm in effort and load
Sir you are saying that M. A = L/E
Then what is M. A = theta×V.R
Both are correct
Constant. (⌒o⌒)
M.A = load/effort
M.A = eta x V.R
eta is the unit of efficiency .
Sir , said eta not theta bro .
Thanks you sir you tach like no others, abhi 1 week me exam hai whish me luck
Thank you so much sir 🙏
Thank u sir so much ........
Sir tnsn kb banega
Thanks
Thankyou sir🎶
Sir in my book there is a tackle tied to hook of lower block and effort is applied upwards
Good explanation sir
11:43 🤣
Excellent video
Sir some days are left for exam so please say the effect of load of pulleys on M.A , V.R and efficiency
WHY WE DONT COUNT 4RTH TENSION
Same question
11:37 😂😂
