How do i measure static friction on metals in the laboratory?
I been looking on how to measure static and dynamic friction between metals in the laboratory. So far, most of the books recommends using either a dynamometer or a pin and disc machine. But these 2 apparatus only measures kinetic friction. So how do i measure the static friction. And please dont say weight and pulley system 
I’ve had to estimate static friction before. What I did was to put a part on a plate and tilt the plate until the part started to move. I took the static friction coefficient to be the inverse tangent of the tilt angle.
