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
