Solution Video 6/121

Proff.

On this video, the answer that was put down for w doesnt correspond to the numbers used.
I tried to do the calculations, i think there s a little mistake with Ic, actually two.
The way i see it Ic= Mr^2+Mr^2+4( (mr^2/12)+m(r/2)^2+mr^2)
Ic= 2Mr^2+(16/3)mr^2
And this would give the recorded answer for w..w=13.2 rad/s

Please let me know if this is not true.
Thanks

Please see the note that appears midway down on the Video Solution Module page for Problem 6/121. This note addresses your point (be sure to click on the link provided there). The equation for I_C there agrees with your I_C equation.
