## Homework Statement

[PLAIN]http://img15.imageshack.us/img15/7379/unledtzc.png

(The rods are of length L, there is no friction, massless rods, yadee yadee yada)

At a certain angular speed [itex]\omega[/itex], the counterweight performs uniform circular motion. Show that [itex]\omega[/itex] and [itex]\theta[/itex] are related as follows:

[itex]\omega^2 \cos{\theta} = (1 + \frac{2m'}{m}) \frac{g}{L}[/itex]

## Homework Equations

[itex]T_1 = L m \omega^2[/itex]

[itex]\cos{\theta} (T_1 - T_2) = g (m + m')[/itex]

## The Attempt at a Solution

(Working backwards) Combined above to get

[itex]T_2 \cos{\theta} = m' g[/itex]

which makes a lot of sense, but I'm not sure if the procedure was right
