SUMMARY
The coefficient of sliding friction can be determined using the maximum angle of inclination at which an object remains in equilibrium. In the discussed scenario, a flat stone on a 30-degree incline cannot have its coefficient calculated without confirming that this angle is the maximum angle (A_max) before sliding occurs. The coefficient of friction is calculated using the formula tan(A_max). If the angle is arbitrary and less than A_max, the coefficient cannot be determined.
