Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.

Question

The figure shows a bicycle wheel resting against a small step whose height is \( h = 0.100 \, \text{m} \). The weight and radius of the wheel are \( W = 20.0 \, \text{N} \) and \( r = 0.390 \, \text{m} \). A horizontal force \( \vec{F} \) is applied to the axle of the wheel. As the magnitude of \( \vec{F} \) 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?

**Diagram Explanation:**

- The image depicts a bicycle wheel with its axle aligned horizontally and supported against a small step.
- The radius \( r \) of the wheel is shown from the axle to the outer edge.
- The wheel rests on a step with height \( h \).
- A horizontal force \( \vec{F} \) is indicated by an arrow pointing rightward on the axle.
- There is a normal reaction depicted at the contact point on the step.

This illustrates a scenario where you need to calculate the force required to lift the wheel over the step.
