Consider a light rod of negligible mass and length L pivoted on a frictionless horizontal bearing at a point O . Attached to the end of the rod is a mass M1 . Also, a second mass M2 of equal size (i.e., M1 = M2 = M) is attached to the rod (2L/7 from the lower end). What is the moment of inertia I about O?
1. I =(25/16)M L^2
2. I =(85/81)M L^2
3. I =(65/49)M L^2
4. I =(10/9)M L^2
5. I =(58/49)M L^2
6. I =(26/25)M L^2
7. I =(5/4)M L^2
8. I =(13/9)M L^2
9. I =(106/81)M L^2
10. I =(74/49)M L^2
