So I did I = Ia +Ib+Ic+Id. Since it's rotating through mass A, I set Ia = 0. I then did I = (.5)(230/1000)(8/100)^2 + (.5)(300/1000)(sqrt[(10/100)^2 + (8/100)^2)])^2 + (.5)(230/1000)(10/100)^2
I got that I = 0.004346 kg * m^2
Does this seem right?
Or I suppose I shouldn't use the .5 so
I =...
This is the math I did when I rearrangedto solve for w, angular velocity. I used I = mr^2. I got w = 2.27995. The units would be the sqrt of(J /kg*m^2), which ends up just being 1/sec. to get the answer in rpm, I figured I would multiply w by 60sec (to get w = 136.797, but this wasn't right
