You are given a thin rod of length 1.4 m and mass 1.8 kg, a small lead weight of 0.60 kg, and a not-so-small lead weight of 1.0 kg. The rod has three holes, one in each end and one through the middle, which may either hold a pivot point or one of the lead weights. How do you arrange these objects so that the resulting system has the maximum possible moment of inertia?

Place the pivot point in one end, the 0.60 kg lead weight in the middle, and the 1.0 kg lead weight in the remaining hole.

Place the pivot point in one end, the 1.0 kg lead weight in the middle, and the 0.60 kg lead weight in the remaining hole.

Place the pivot point in the middle, the 0.60 kg lead weight in one end, and the 1.0 kg lead weight in the remaining hole.

What is that moment of inertia (in kg ยท m2)?
