Determining the Coefficient of Friction

2013-10-2 · fr*cos(a)*W = sin(a)*W Dividing both sides of the equation by W and cos(a), we get the equation for the static coefficient of friction fr fr = tan(a) where tan(a) is the tangent of angle (a) and equals sin(a)/cos(a). There are mathematical tables for determining the tangent, sine and cosine of various angles. Example calculation
