    a flywheel has a mass of 20kg and radius of gyration 95mm
    what torque would be needed to accelerate it from rest to 800rev/min in 40seconds??

    This can be found pretty easily on google, it also sounds like a textbook question.

    What do you think is invloved in solving this?

    everything is given. what else do you need? Find I & accl.
    torque = I.Accl
