Question

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?

The image depicts a bicycle wheel that is in contact with a step. The wheel is shown with a force \( F \) applied horizontally. 

Key elements of the diagram:
- **Wheel:** The wheel is shown in profile, with spokes radiating from the center.
- **Force \( F \):** An arrow indicates that a force \( F \) is applied horizontally to the right. It acts at the axle of the wheel, which is at the center of the wheel's circle.
- **Radius \( r \):** A line is drawn from the center of the wheel straight downward to show the radius \( r \) of the wheel.
- **Step:** The wheel is in contact with a vertical step.
- **Height \( h \):** The height of the step is indicated by a vertical line labeled \( h \).

This diagram likely illustrates concepts related to the physics of motion, such as static equilibrium or the torque needed to overcome an obstacle.
