COF Friction Tester Principle

The COF Friction Tester operates on a simple yet effective principle. Two samples are placed in contact, with one fixed on a flat surface while the other is subjected to force via a sled. The friction force is measured when the two materials slip against each other. The system calculates both static and kinetic friction coefficients using the formula:

$\mu =\frac{f}{N}$

Where:

• μ is the coefficient of friction
• f is the force of friction
• N is the normal force
