I have this homework question that I an having a lot of trouble with. I am not sure if anyone could help, but here it is:(adsbygoogle = window.adsbygoogle || []).push({});

Using the definitions of torque and lever arm and the fact that the system is in equilibrium, derive this formula-

Xo= m1x1 + m2x2 + m3x3

....... m1 + m2+ m3

So, I know all the different formulas for torque and the levers etc... but I can't figure out how to turn them into this formula?
