### 14.10 Coefficient of friction

There are three options for determining the coefficient of friction μ:

- Own input of constant value.
- Constant value calculated according to AGMA925 equation 85.
- Constant value calculated according to AGMA925 equation 88.

The value for the coefficient of friction can be entered directly by checking the box
at the side of the field or accept the program default for a constant value.
Alternatively, the user may request a variable coefficient of friction in which case
Scoring calculates according to AGMA925.
