Okay thank you both, I think I understand it now.

I did I=mr^2=1.4(0.83)^2=0.96446kgm^2 that was my first attempt and it didn't work however upon looking further into my notes I found the equation I=(1/3)mr^2=(1/3)(1.4)(0.83)^2=0.3215 and that did work, but I don't quite understand it.

Homework Statement A ceiling fan consists of a small cylindrical disk with 5 thin rods coming from the center. The disk has mass md = 2.9 kg and radius R = 0.22 m. The rods each have mass mr = 1.4 kg and length L = 0.83 m. 1) What is the moment of inertia of each rod about the axis of rotation...
