I hope I managed to post my question the right place!

I have a body consisting of a bunch of mass-points in ℝ[itex]^{3}[/itex], and when torque is applied to this body, I'm interested in finding the force that must have caused the torque based on the point of application and the torque vector, which are given.

I see the form;
[itex]\tau[/itex] = r[itex]\times[/itex]F
quite often, such as it is seen in wikipedia (which offers a nice overview btw).

I understand that it is not possible to calculate F, but I find it hard to believe that F[itex]_{\bot}[/itex] is impossible to calculate since it should be unique, yet I don't see such an equation anywhere. Any pointers would be greatly appreciated!
