In the diagram shown below all three rods are of equal length $L$ and equal mass $M$ . The system is rotated such that $rod B$ is the axis. What is the moment of inertia of the system?

Options:

Answer:

Solution:

Since the width is negligible, the moment of inertia of $B$ is zero along its length. $I_{A} + I_{C} = \frac{m L ^{2}}{12} + \frac{m L ^{2}}{12} = \frac{m L ^{2}}{6}$
