Problem

A rigid body of total mass

M

has a known rotational inertia

I_{cm}

about an axis that passes through its center of mass. Which expression gives the rotational inertia

I'

of the body about a second axis that is parallel to the first and a distance

d

away? a)

I' = I_{cm} - Md^{2}

I' = I_{cm} + 2Md^{2}

I' = I_{cm} + Md^{2}

I' = Md^{2}
