"WebCalculate its moment of inertia. Step 1: The density is defined as ρ = m/V, so in terms of mass we have: m = ρ*V. Now, because in our example we have a rod, we have a one-dimensional object, so instead of Volume we use Length. And instead of density ρ, which is defined for three-dimensional objects, we use λ, which is linear density. " - Moment of inertia of wood beam
