Gravitational Radiation Calculation from Rotating Rods

[Stas]

anybody know link where i can see how to calculate the power of the gravitational radiation emitted from a rotating rod?

MTW's "Gravitation" gives a formula on pg 980.

In geometric units, the formula is:

L_{GW} = \frac{2}{45} M^2 l^4 \omega^6

where M is the mass of the bar
l is the length of the bar
\omega is the angular frequency of rotation of the bar, \frac{2 \pi}{T}, where T is the period of rotation of the bar.

Converting this to standard units we get

L_{GW} =\frac{2}{45} \frac{G}{c^5} M^2 l^4 \omega^6

the added constants are c, the speed of light, and G, the gravitational constant.
