In measurement of coefficient of friction on an inclined plane, the
equation for the coefficients of both static and kinetic friction have
the same form, that is, (mu) = tan A, where A is the angle of incline.
Now, theoretically, this mu can have a value anywhere from 0 to
infinity, but it hardly exceeds 1. I saw only one value that was greater
than 1 in the table of coefficients. So, I imagine it is the physical
properties of matter that set this limit. I guess my question is: What
sets this limit? Thank you in advance.
