Problem

A thin uniform rod of length

0.80\,\text{m}

and mass

0.50\,\text{kg}

is rotated about an axis parallel to the rod and

0.20\,\text{m}

from its midpoint. The rotational inertia about this off-center axis is measured to be

0.070\,\text{kg}\cdot\text{m}^2

. Determine the rod’s rotational inertia about an axis through its center.
