The laws of adhesive wear, commonly referred to as Archard’s law can be expressed as _________.

(If ‘Q’ is the total volume of wear debris produced, ‘W’ is the normal load, ‘L’ is the sliding distance, ‘H’ is the hardness of the softest contacting surfaces being worn away, and ‘k’ is a non-dimensional wear coefficient dependent on the materials in contact and their exact degree of cleanliness)

- Q = kWL/H
- Q = kW/LH
- Q = kHW/L
- Q = k/LWH

Option 1 : Q = kWL/H

**Explanation:**

According to the Archard’s law of adhesive wear, the wear volume (Q) is proportional to the normal force (W), the sliding distance (L), and inversely proportional to the hardness of the softer of contact partners (H)

\(Q\propto \frac{WL}{H}\)

\(Q=\frac{kWL}{H}\)

Where k is the non-dimensional wear coefficient also called adhesive wear coefficient.
