THE BUBBLE MOMENT

A physical pendulum is composed a rod of length 26 cm and radius 3.2 cm suspended downward from one of its ends. At the bottom, free end, there is a large, circular bubble of the same radius as the rod so that it is wholly within the rod, but as far towards the bottom as possible.

(a) If the rod has a density of 9 g/cm3, what is its mass?

(b) Find its center of mass if the rod is suspended at the origin .

CM = 0  x̂ + 0  + ___  ẑ

*Can't figure out z component*

(c) Find its moment of inertia around the origin.
