Problem 65

A disk of radius R has an initial mass M. Then a hole of radius R/4 is drilled, with its edge at the disk center (Fig. 10.29). Find the new rotational inertia about the central axis. (Hint: Find the rotational inertia of the missing piece, and subtract it from that of the whole disk. Youll find the parallel-axis theorem helpful.)
