so you need a spring formula?!?

the basic formula is F=-k*d      k is the Stiffness of the spring and d the distance

expanded it's (as code)

Vector2 force = -Stiffness * (dist / dist.Length()) * (dist.Length() - defdDistance);

defdistance it the default lenght of the spring

btw i don't know why you just use the farseer spring joint
