general uniform acceleration question

If an object is in uniform circular motion, can it be assumed that there will be no net force in the vertical direction (aka no net forces for the y component)?

$\displaystyle \sum F_y = 0$ if the UCM is restricted to a horizontal plane

Gyroscopes

This reads a bit like like a query regarding gyroscopes,
just approaching from a different direction.

A simple uniform circular motion, will not produce a net force perpendicular to the plane of the circle.

However if you impose a second circular motion upon your first,
in a plane perpendicular to the first,
you will find that that it produces a torque trying to rotate the system,
in the plane perpendicular to the other two.
