The drawing shows a wire tooth brace used by orthodontists. The topmost tooth is protruding slightly, and the tension in the wire exerts two forces and ' on this tooth in order to bring it back into alignment. If the forces have the same magnitude of 17.0 N, what is the magnitude of the net force exerted on the tooth by these forces? (the angle is 16.0 degrees)
what angle? You have to figure the force normal to the tooth.
