Evaluating tribological properties such as friction coefficients, friction forces, and torques for arbitrary material pairs, with high precision is crucial for multiple areas of research and industry.

Measuring torque when installing threaded fasteners is the best indicator of future joint performance, right? Actually, bolt tension is a better performance indicator, but measuring torque is far ...

I'm trying to calculate the friction torque between to flat surfaces rotating against one another, and can't find any examples of this particular problem for guidance--only for rotating cylinders.
