In the morning i get this idea ....the simplest way to determine friction force between two sliding surfaces.

The angle of the book changed between sliding and the angle measurement.
The method can give a rough approximation of the coefficient of static friction, but it should be done more carefully.

Grat, you just (re)discovered the concept of "angle of friction".
Used in intro labs to estimate static and kinetic friction.
