The moment of inertia of a thin uniform rod of mass M and length L about an axis passing through its midpoint and perpendicular to its length is I_(0). Its moment of inertia about an axis passing through one of its ends and perpendicular to its length is ............. |

Answer» `I_(0)+(ML^(2))/(2)` The MOMENT of inertia about the MIDDLE axis is `I_(0)`, Now ACCORDING to parallel axis `I=I_(0)+Md^(2)` putting `d=(L)/(2)` `I=I_(0)+M((L)/(2))^(2)` `therefore I=I_(0)+(ML^(2))/(4)` |
