I had a problem with finding the moment of inertia. I have a rod and it has linear density[tex]\lambda=4.0kg[/tex] and the equation for its moment of inertia is [tex]I=\frac{1}{12} ML^2[/tex] now I have an axis at the center of mass of a rod the rod has a total length [tex]L=4m[/tex] so in my equation I would have to substute [tex]\lambda L=M[/tex] now the thing that I dont understand is if my center of mass horizontal cordinate is [tex]2m[/tex] the length I multipy by lambda should be 2m correct?(adsbygoogle = window.adsbygoogle || []).push({});
