1. The problem statement, all variables and given/known data Calculate the rotational inertia of a meter stick, with mass 0.68 kg, about an axis perpendicular to the stick and located at the 21 cm mark. (Treat the stick as a thin rod.) 2. Relevant equations I = integral of radius squared with respect to mass 3. The attempt at a solution I'm not quite sure how to explain my issue here, but I think all I need is to see this worked out, and then I could probably understand the nature of these problems. Thanks.
