Question:

The ratio of pressure force L to friction force D for an object A in contact with object B is L/D = 10. what is the coefficient of friction of A/B?

Answer:

Coefficient of friction equals:

$$\mu = \frac {F _ {f r}}{N}$$

where $F_{fr}$ friction force, $N$ is normal force.

The ratio of pressure force L to friction force D equals:

$$\frac {L}{D} = \frac {N}{F _ {f r}}$$

Therefore:

$$\mu = \frac {1}{\frac {L}{D}} = \frac {1}{10} = 0.1$$

Answer: 0.1
