However it is possible to find tables in the literature for friction coefficients between various materials.

Coefficient of friction granite on steel.

Coefficients of friction between materials are best determined through testing. Steel to steel. Tribology materials surfaces interfaces. Coefficient of sliding friction for most rocks varies between 0 8 and 0 5.

Below are provided a small number of values showing approximate values of friction coefficients to be used for steel screw fastened connections. μ static μ s or kinetic μ k frictional coefficient. Concrete to soil rock. Glass on glass 0 4 rubber on concrete 0 75 steel on steel 0 55 angle of internal friction rock 30 sand 30 40 gravel 35 silt 34 clay 20 loose sand 30 35 medium sand 40.

First you tape the low g accelerometer on the end of the surface in this case a slab of granite. Ref links 1 below the american gear manufactures association agma recommends a value of between 0 12 0 15 for hydraulically expanded hubs and 0 15 0 20 for shrink or press fit hubs. The coefficient of friction is required in calculating tightening torques and resulting bolt tensile forces and stress and in calculating the resulting friction between the connected surfaces. Concrete to steel.

The frictional force can be expressed as. Steel to teflon plate. Brick masonry on rock. The coefficient of kinetic friction is generally lower than the coefficient of static friction on the same surface.

The coefficients of friction are independent of the surface area in contact. Where μ s is the coefficient of static friction and μ k is the coefficient of kinetic friction. The friction force is the force exerted by a surface when an object moves across it or makes an effort to move across it. F f μ n 1.

A value of 0 60 would be a good number for general use. For example static friction can prevent an object from sliding down a sloped surface. F f frictional force n lb. The coefficient of kinetic friction for curling ice.

The following friction coefficients shall be considered in calculating the sliding friction forces. The coefficient of static friction typically denoted as μ s is usually higher than the coefficient of kinetic friction. Coefficient of friction to 0 25 to 0 3. These companies can provide surface coating fluids containing particles to increase the coefficient of friction i e.

The value of μ s is generally higher than the value of μ k for a given combination of materials. Friction and wear characteristics of steel on rock under water and oil based lubricated sliding conditions. Static friction is friction between two or more solid objects that are not moving relative to each other.
