    How Does Changing the Axis Affect Angular Acceleration of a Disc?

    Hi, I am a little stuck on this question from a PPOD paper I am doing all help appreciated =) Homework Statement A solid circular disc of mass 6.6kg and radius 0.25m rotates about an axis which coincides with its diamter. Its angular acceleration is found to be 6.7rad/s. The axis of...

    Moment of Inertia for a solid circular disc

    I got it eventually, I was just looking at it the wrong way round, ended up with Io=Ic + md^2 = 0.25mr^2 + mr^2 = 1.25mr^2 feel very stupid now after seeing how easy it was!

    Moment of Inertia for a solid circular disc

    hi that's really helping, I just realized that it in my confused state I forgot to include that the question before this was to prove that, a disc rotating about an axis that coincides with a diamter is I=.25mr^2. and I was wondering would this give me the value that I would sub in for D in...

    thanks :) I am vaguely familiar with it but I am not exactly great at it.

    Moment of Inertia for a solid circular disc

    hey kinda new to this and I know the rules say I am not allowed to be told how to do this but I am totally stumped and its to be handed in tomorrow. I've looked through everything and cannot find out how to do it anywhere I am starting to think there is a typo in the question paper :S show...
