Problem
A uniform rod of length L can rotate freely about four different axes:
• Axis 1: through its center and perpendicular to its length
• Axis 2: through one end and perpendicular to its length
• Axis 3: through a point one-quarter of the length from one end and perpendicular to its length
• Axis 4: along the rod’s length through its center
Which of the following correctly ranks the rotational inertias I1,I2,I3, and I4 from greatest to least?
(a) I4>I1>I3>I2
(b) I2>I1>I3>I4
(c) I2>I3>I1>I4
(d) I1>I2>I3>I4
