Hey, one radian is 180 degrees / pi, which is about 57.3 degrees. In other words, 360 degrees is equal to 2*pi radians. Keep these numbers in mind, they may save you in future tests / quizzes!

Just curious, I wonder if you could get an approximation of the mechanical work done by the propeller (when under load) by measuring the voltage and amps supplied by the electrical controller. Clearly some would be lost to internal friction / conversion efficiencies, etc.

Don't forget the parallel axis theorem. Increases moment of inertia by rotating the hoop about another axis entirely. Meanwhile...I basically agree, the hoop may be the shape with the highest intrinsic moment of inertia. Because all the mass in a hoop is some distance away from the center of...

Am doing lots of college level physics tutoring these days, and getting set to go back to school this fall for a PhD program (Aerospace Engineering, not exactly physics but we get lots of physicists joining us!). Great forum to get answers to tough questions, I just had to join. Hope I can...
