Hello everyone if someone can helo me out here(adsbygoogle = window.adsbygoogle || []).push({});

I have a rotating shaft wiht a disc mounted on it.The moment of inertia of the total system is 170 kgm2.It is rotating with a veolicty of 20 deg /sec.i want to bring it to stand still within 80 deg travel from the application of brakes

I=170 kgm2

wi=20 deg/sec=0.34 rad/sec

wf=0

Δt=4 sec(taken from the fact that it is moving at speed of 20 deg/sec,80 deg/sec will be covered in 4 sec.Please correct as i m not sure abt this value)

So

T=Iα

T=I(Δω/Δt)

T=(170) (0-0.34/4)

T= -14.45Nm

Please correct and help
