# Wheel with radius and mass

#### Eagle Eyes

1. Homework Statement

A wheel of radius R and mass M is dragged over a step of height h by force F applied horizontally at its center. What is the maximum value of F required so that the wheel climbs over the step? (Hint: wheel climb is equivalent to a rotation around the point of contact with the step.)

2. Homework Equations

Not available.

3. The Attempt at a Solution

I have no idea how to start this. But i would use potential energy perhaps?

You're going to want to consider the Σ Torques > 0 needed to pivot over the edge of the step as the hint suggests.
