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.It's constraint motion
Write the NLM equation for both blocks
Arey nahi bhai
I think this is
Given information
That I hile m2 moves with a
m1 moves with 2a
They have given an explanation but I don't understand it
its constraint eqn
cause length of thread cannot be change
jo m1 mass wala hai uski string agar x distance move kregi to m2 mass wli 2x kregi kyuki m2 mass se jo pulley attached hai uspe dono side string hai
@arun
i see
so u generally take 2a in qs like these?
@Real potato
yeah
not always 2a
according to condition we decide
taki variables kam ho sake
are you familiar with virtual work method ?
nope
wym
yaha 2a hai kahi 3a bhi ho skta hai 4a bhi ho skta hai it depends on ki ek block ke x move krne se dusra ko kitna move krna pdega taki string length constant rahe
oh no issue ap is chapter me hi ye pdhoge fir aasani se aap ye constraint equations bana paoge
how do u decide how much the other block will move?
the main concept is that string length should remain constant like in this example
if m1 is gonna move down say x distance
then the pulley around m2
the sting there will be streched by 2x
do you get it?
yes thank you
u may close the doubt if its done
how do u do that
