Could some one tell me please how too, or indeed if there is a formula to determine/measure the forces of precession?
Assume w/respect to gyros ?. Google is your friend . There's loads of gyro stuff on the web, some with lots of pictures to guide you through it all and you shouldn't need much more than basic math and common sense to understand it.
No excuses - if you're smart enough to dream up the application and the questions, then you are smart enough to do this yourself
