## Homework Statement

I need to find the rotational kinetic energy of this system in the figure I have provided. Here the spring is rotating with the system at angular speed [itex]\omega[/itex]. The two beads on the wire move vertically, and the third bead is held by two massless rods of equal length L.

## The Attempt at a Solution

Would the moment of inertia for the the whole thing just be

[itex]I_{1,3}=2mL^{2}[/itex]

[itex]I_{2,3}=2mL^{2}[/itex]

[itex]I_{total}=4mL^{2}[/itex]

Any suggestions would be helpful.
