## Homework Statement

I've performed a CFD analysis on a racecar model which has given my forces and torques (about the origin) in x,y,z. I'm struggling with the interpretation of those results. I'm interested in the point along the x axis about which the lift force acts.

Both forces are known, Torque about the origin due to these forces is known, the distances at which the forces act are the unknowns

## Homework Equations

I would state this as Torque

_{(about origin)}= (F

_{x}z) - (F

_{z}x)

## The Attempt at a Solution

As far as I can tell there is 2 unknowns, too many to be solved with a single equation? This is a simplified version of my problem, the car is not symmetrical so there is also torque about the other 2 axis and I have tried to solve the three equations this sets up simultaneously but they are unsolvable, but I believe this is because the force in the y direction would not necessarily act at the same point along the x axis as the force in the z direction. But then putting extra terms in for the different distances means 3 equations and 6 unknowns which leaves the same problem so I'm back to this simplified version.
