JA 2024 PHY + solved

In this when we conserve angular momentum of bigger disc, why don't we add mr^2 (due to small disc) while writing moment of inertia of big disc, as the small disc is attached to the big disc (+solved @Aviationforce )

the disc is attached on a motor shaft which is massless motor shaft is attached to circumfrence small disc is not attached to bigger disc

nvm bro i understood
Aviationforce
Aviationforce•2mo ago
so why do we need to apply the mr^2>
coolguy
coolguyOP•2mo ago
it is

nah read ques your in 11th?

coolguyOP•2mo ago
lemme check
Aviationforce
Aviationforce•2mo ago
come dms ill explain its a simple msitake i also did it
coolguy
coolguyOP•2mo ago
the motor is fixed to the disk bro its given in the question
Aviationforce
Aviationforce•2mo ago
yes agreed
coolguy
coolguyOP•2mo ago
however i know why we dont add mr^2
Aviationforce
Aviationforce•2mo ago
but why do we need to add mr^2to the disc?
coolguy
coolguyOP•2mo ago
yeah i made a blunder
Aviationforce
Aviationforce•2mo ago
why?
coolguy
coolguyOP•2mo ago
cause about the central axis the system is rotating with some omega so about that axis i can write the angular momenta individually for each body if i am unclear then leave this doubt i asked something stupid
Aviationforce
Aviationforce•2mo ago
nothing is stupid man genuine only it odnt matter how others think
coolguy
coolguyOP•2mo ago
real thank you though for acknowledging the doubt
Aviationforce
Aviationforce•2mo ago
isme kya thank you btw you solved? the problem?
coolguy
coolguyOP•2mo ago
yeah yeah just conserve angular momenta cause all torque is internal
