< Prev
Next >

Two uniform rods, A and B, have identical mass and length. Rod A is positioned on the x-axis from $x=0$ to $x=L$, and Rod B is positioned on the x-axis from $x=-L/2$ to $x=L/2$. For which of the following axes of rotation is the rotational inertia of Rod A greater than that of Rod B?

A

The rotational inertia is the same for both arrangements

B

An axis through x=L/2, perpendicular to the rod

C

An axis through the center of mass of each rod

D

An axis through x=0, perpendicular to the rod
