A long pole is rotated around three different rotation axes: central core axis, midpoint axis, and one end axis as shown in figure 2. The pole is easiest to rotate about its central core axis, and it is hardest to rotate around its one end axis.

Analysis:

1. Which axis of rotation the pole obtains the greatest moment of inertia?


2. In which axis of rotation, the pole had the smallest moment of inertia?


3. How do the axes of rotation affect the rotation of the pole? (Hint: Relate it to the moment of inertia.)
