Moment of inertia problem...please help !
Hi,
I have been sat in front of this computer all day trying to work this problem out.
A turbine rota accelerates to 60rpm from rest in 9 revs then the force is removed and it continues to rotate for a further 20 revolutions.
Basically I know the torque is 260Nm
I know the acceleration is 0.35 rads/s^2
I know the deceleration is 0.16 rads/s^2
I need to find the moment of inertia in kgm^2
And i need to find the bearing friction in Nm
Please help, think my head is going to explode
