The figure shows a bicycle wheel resting against a small step whose height is h = 0.130 m. The weight and radius of the wheel are W = 16.0 N and r = 0.340 m. A horizontal force  is applied to the axle of the wheel. As the magnitude of  increases, there comes a time when the wheel just begins to rise up and loses contact with the ground. What is the magnitude of the force when this happens?
