Yes I've included the weight of the metal block itself. I'm not sure what you mean by unaccounted mass? Sorry those values were just example values to show the the COF was decreasing. The type of values I am actually getting are: Normal force: 69.5N, 118.56N, 167.6N, 216.7N Static COF: 1.503...

I expect an increase of the actual area of contact (at the surface asperity level) as I increase the normal force, therefore more asperity junctions would need to be broken leading to a higher COF. I am using a pneumatic ram to apply a horizontal force to a block of metal with a rubber...

In my experiments, on a flat plane, when I incrementally increase the normal force acting on a rubber block, I am measuring a decrease in the static coefficient of friction. I am also measuring the friction force, which increases as normal force increases BUT this is not a proportional increase...
