Friction - Friction Coefficients and Calculator

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

resisted by the friction between the components. A joint of this kind is called a friction joint. If the clamping force is not sufficient to create the friction needed, the screw will also be exposed to the shear load. Joints are frequently designed for a combination of tensile and shear loads. The screw is made up of the shank and the head.

Static Friction in Slip Critical Bolt Joints

The maximum friction force that is achievable is the one right before the slipping point (see Figure 4). The friction and pull force is proportional until it starts to slip. After that the friction is slightly lowered, but constant, and the object will start to accelerate.[1] Figure 4. Graph with friction force on y-axis and pull force on x-axis.
