APFIVE Rotational Inertia of a Modified Disk
A uniform disk of mass M and radius R has a small hole of radius R/4 drilled at a distance of R/2 from the center. What is the moment of inertia of this modified disk about an axis perpendicular to the disk through its center?
A
MR²/2 - M(R/4)⁴/R²
B
MR²/2 - M(R/4)²/R²
C
$$\frac{1}{2}MR^2 - \frac{9}{512}MR^2$$
D
MR²/2 - M(R/4)²(R/2)²/R²
