APFIVE Rotational Inertia of Uniform Rods
Two uniform rods of identical mass and length are arranged differently: Rod A extends along the x-axis from x=0 to x=L, while Rod B extends from x=-L/2 to x=L/2. About which axis would Rod A have a greater rotational inertia than Rod B?
A
An axis through the center of mass of each rod
B
An axis through x=L/2, perpendicular to the rod
C
An axis through x=0, perpendicular to the rod
D
The rotational inertia is the same for both arrangements
