Is it unreasonable to expect a coefficient of friction to exceed unity ?

Explanation

To determine whether it is unreasonable to expect a coefficient of friction to exceed unity, we can analyze the concept of the coefficient of friction step by step.

### Step 1: Understand the Definition of Coefficient of Friction
The coefficient of friction (μ) is defined as the ratio of the frictional force (F_friction) to the normal force (F_normal) acting between two surfaces in contact. Mathematically, this can be expressed as:
\[ \mu = \frac{F_{\text{friction}}}{F_{\text{normal}}} \]
