Friction and Friction Coefficients - Engineering .

The friction force is the force exerted by a surface when an object moves across it - or makes an effort to move across it.. The frictional force can be expressed as. F f = μ N (1). where. F f = frictional force (N, lb). μ = static (μ s) or kinetic (μ k) frictional coefficient. N = normal force between the surfaces (N, lb) There are at least two types of friction forces

However, in the forks configuration, we lose a bit of MA, because our force to fulcrum distance is reduced by the length of fork we drive past the fulcrum, in this case that is 3.5". Therefore we end up with 30" bar minus 3.5" for a force to fulcrum length of 26.5". So our MA is 26.5 / 2, which equals 13.25:1, still significant, but reduced from the adze application. What's important ...
