Consider a rigid dumbell with two masses, each of mass m, spaced a distance d apart. As a reminder, the momentum of inertia for a mass m at the end massless rod of length L is I = mL^2. -- Find sqrt(w^2), the rms angular speed of the dumbbell about a single axis (taken to be the x axis), assuming that the dumbbell is lined up on the z axis and is in equilibrium at temperature T.
