In the diagram shown below all three rods are of equal length and equal mass . The system is rotated such that (\operatorname{rod} B) is the axis. What is the moment of inertia of the system?
Options
- A(\frac{M L^2}{6})
- B(\frac{4}{3} M L^2)
- C(\frac{M L^2}{3})
- D(\frac{2}{3} M L^2)
Correct answer
A. (\frac{M L^2}{6})
Step-by-step solution
Since the width is negligible, the moment of inertia of is zero along its length.
(I_A+I_C=\frac{m L^2}{12}+\frac{m L^2}{12}=\frac{m L^2}{6})
