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?
Homework Equations
I=(sum of)mr^2
The Attempt at a Solution
I tried using the above equation multiple different ways, with just the mass and length of the rods, with the mas of the rod and the disk and the length. With the length plus the radius. The homework I have won't accept a wrong answer but I just don't really understand what I am doing wrong could someone please help?
