Homework Statement
Find moment of inertia of a washer with a hole of radius r/2.
Homework Equations
Moment of inertia = integral of x^2 dm
γ = m / L
The Attempt at a Solution
I think I can find the moment of inertia of the washer using integral of x^2 dm. So, I know my γ = m / L = m / (R/2) = 2m / R
I = (2m / R) * [((R/2)^3 / 3) - 0] = (m * R^2) / 12
However, that is not correct. Where am I going wrong?
