Yup, adds up the contribution that each wheel adds to the turning moment (M=f*d) less the resistance of each wheel to the turning moment.

Summary

Ever wonder why your four-wheel-drive system won't turn? You'll never need to wonder again. Drive Train Basics gives a full explanation, complete with mathematical equations, to allow you to design a drive train that will turn without a problem.
