Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.Yeah but you need to find the ans in terms of M and m
Han T aa gya and acc to me 4T hona chahiye
The values u see written below are the answers
Ha to isme doubt kya h apko
Answer T dia hai par aana 4T chahiye , am I wrong or the book
T is the tension in string here due to m
To fir plus hote hote man ke upar wali string mein 4T tension aa jayegi
ig they would have taken it the other way around, taking T for the first string, then T/2, then T/4
instead of 4T, 2T ,T
This is the soln given , so idts it's t t/2 t/4
@g-sus @Gibraltor any updates?
Anyone ?
@Gyro Gearloose any inputs?
Its t+2t+4t I think?
Ig the equations would be: T-Mg=7Ma (Man)
Assuming platform is massless, acceleration of platform=acceleration of mass*(1/3) or something (Using string constraint)?
U will take 4T for man tho, if it is T for man then it would be t t/2 t/4
Even I am getting 4T, if u consider T , t/2 t/4 total thing will change so it won’t be 7T but same ans ig
True.
is it possible that plank is exerting 3T?
Total 7T , 4T from man and 3T from plank
my bad , all of the 6T by plank and T by man
O how pls explain
Just a thought
O I thought u meant it like a fact sorry, but I don’t think so tho? When we draw fbd for plank it isn’t evident that 6T is by plank only
Did u ask ur teacher mayb?
nah i couldnt
I’ll try asking my teacher then, is that fine?
Yeah ofc
Correction: In my calculation of T that - 49 m^2 g gets cancelled
we good?
This q. From? Hcv or DC Pandey
Hey I'll review it in a few and close the thread , thanx.
Question from Ashish arora
hey @Ishizora i sae your solution and i have done the same thing as well and obtained same values of T a and b , the main doubt here is what force is the man exerting, T,4T or 7t
man being at rest wrt platform will only have to exert the force which is not balanced out just by the normal
normal acting on the man is 3T which leaves T as the force to be applied in order for man to be at rest wrt platform
aight, got it, big thanx
