In the last question minimum weight is required so tension will became maximum between block and pully , Hence we put the value of tension as maximum in formula to find the min weight .
At 1:09:46 , how can you write tension T1 = 50 Kg ??? It should be 500 N. Similarly at 1:12:24 , how can you write T2 = 29.62 Kg ?? The unit of tension is Newton. I guess due to this mistake, final answer is wrong. Although the process of solving the whole question is right.
Angle of contact must always be less than 180° In the very first ques. of belt friction,sir has taken it 210°. Where it should be 180°-30°=150° .. correct me if I'm wrong!!
Sir I have one dout you neglected weight of both belt as well as pulley. ? If pulley weight is neglected than how normal reaction will come. If you consider this then where is it's value in derivation. W is not there

01:04:30 π= 180 and 2π=360
1:13:05 is what i like about sir Apuroop. Most educators wont admit that. Such a humble Sir❤
Thank you so much sir for giving us these free class thank you very much sir❤️❤️❤️❤️
Amazing explanation sir ❤️❤️❤️
Sir, in 19:53 if we are considering very small piece of belt then the curve will be approximately straight right? ∴ dθ will be very small.
yes

thank you so much sir, itna acha se aj tak khi nhi pdha sir apke wajha se mechanics bhut easy lag rha hai sir..
Iam from sri lanka. Amazing explanation sir ,goof luck
thank you sir for the free class
Sir in 2nd math you say thita=360+180
Is it should be 2π+π=3π??
yes
Yes
Well teaching. ❤❤❤
where i find the lecture notes?
at 1:05 Theta = 360 + 180 = 2π + π = 3π
Why you write 3π/2 ?
Yes bro
sir ne mmistake kr di h thodi 3pi hi lena h
I agreed
it was corrected at 1:22:00
Still he didn't converted into radians@@vkporganic2409
Theta = 360 + 180 = 2π + π = 3π
Why you write 3π/2 ?
Ok sir samaj aa Gaya aage video me 😂
kya samaj aaya? it should be 3pie
@@anweshakarmakar4014 ha sir ne aage thik kar diya hai.... Dekh lena aage video me👍
`i have the same doubt but my ans is according to 3pie
Ufff.... Awesome❤❤❤❤❤
1:04:32 the angle taken in radian is wrong 360°=2π
180°=π....
sir ka to andaaz hi alag h ...

More detailed than english variants!
unacademy is the best
Nicely explained
Aap Bhagwan hai sir hamlog k lia
Thank you sir 💐👍👌
Just love it
Sir, big fan sir!
First question mein angle 240 kyu nai lia. Ek taraf ka angle count kia dusri taraf ka kyu nai kia? Can anybody explain?
Angle of contact must always be less than 180°
In the very first ques. of belt friction,sir has taken it 210°.
Where it should be 180°-30°=150°
.. correct me if I'm wrong!!
No bro wherever rope will be it will be considered as in theta
Why?
Best 👌👌
Paid course owners r b like:😠😠😡😡
Actually 😂
amazing sir, I am from RRCAT Indore
great concept sir
I am watching part 13😁😁
Sir I have one dout
you neglected weight of both belt as well as pulley. ?
If pulley weight is neglected than how normal reaction will come.
If you consider this then where is it's value in derivation.
W is not there
In question no. 1 if we lift the block without using pulley then we have to apply only 100N then why we are using pulley
Sir calculator radiant mai rakna ha
05:40
THANK YOU SO MUCH............

At 1:13:05 i think it should be 150 and not 120 theta
It confused me for a while...but I guess it 120 is right ...you can try using construction with protractor i guess you will get same angles
@@pushpakbhirud1744 yes it is right
1:07:16 sir be like aayein

How much 3π/2 in degrees
270
Sir log ka derivative toh positive hoga
Aapse padhne se acha ne padhne hai
What are you talking about??
