Problem M. 369. (May 2017)

M. 369. Measure the rotational inertia of a AA battery (Mignon) about its axis of symmetry (\(\displaystyle a\)), and about the axis (\(\displaystyle b\)) which is perpendicular to the previous one and goes through the centre of mass of the battery.

Give the result in terms of \(\displaystyle mR^2\) and \(\displaystyle mH^2\). (\(\displaystyle R\) is the radius of the battery, \(\displaystyle H\) is its height and \(\displaystyle m\) is its mass.)
