1. The problem statement, all variables and given/known data

i need to find the rotational inertia of a rod about a pivot. The rod is of mass M and length L and is attached to a pivot of negligible friction located at a distance of L/3 from the left end of the rod.

2. Relevant equations



3. The attempt at a solution

i know that if the pivot were in the center it would be (1/12)ML and if the pivot were on the end it would be (1/3)ML, but i dont know how to find it at (L/3). can anyone help me? id really appreciate it! thanks.

Try the parallel-axis theorem.
