Problem

A laboratory group measures the rotational inertia of a uniform rectangular plate (mass

1.2\,\text{kg}

) about an axis

0.15\,\text{m}

from its center and parallel to a central axis. The measured value is

I' = 0.090\,\text{kg}\cdot\text{m}^2

. A reference table lists the accepted value for the plate’s central-axis rotational inertia as

I_{\!\text{ref}} = 0.060\,\text{kg}\cdot\text{m}^2

. Calculate the experimental value of the plate’s central-axis rotational inertia and determine the percent difference between this value and

I_{\!\text{ref}}
