    How do I determine torque required to accelerate

    OK, thanks for that. I'll give it a go

    How do I determine torque required to accelerate

    No, that's where I'm stuck...I am on the right track though with my assuming I need the moment of inertia? I could guess that I calculate the "I" for each of the smaller objects then take the average?

    How do I determine torque required to accelerate

    What I have so far is w = 50rpm = (50x2pi)/60 = 5.23 rad/s w = wo+at a=(5.23-0)/5 = 1.046rad/s^2 T=mr^2a T=68x.05x1.046 0.17782Nm But now I'm thinking I need to be using T=Iga (Moment of Inertia x acceleration) but I can't work out how to calculate the moment of inertia...i've only ever done...

    How do I determine torque required to accelerate

    Referring to the attached diagram, how do I determine the torque required to uniformly accelerate the object about the vertical axis XX from rest to 50 rpm in 5 seconds?
