Coefficient Of Friction Of Aluminum With Granite

N normal force between the surfaces n lb there are at least two types of friction forces.

Coefficient of friction of aluminum with granite.

F f frictional force n lb. The coefficients of friction are independent of the surface area in contact. F f μ n 1. μ static μ s or kinetic μ k frictional coefficient.

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. First you tape the low g accelerometer on the end of the surface in this case a slab of granite. The coefficient of kinetic friction is generally lower than the coefficient of static friction on the same surface. The friction coefficient of graphite particulates reinforced in pure aluminium up to 5 wt decreases with increase in sliding velocity and sliding distances is reported by rajesh et al.

These companies can provide surface coating fluids containing particles to increase the coefficient of friction i e. From different studies it is revealed that various field process wear parameters influencing wear coefficient of friction of amc s. Coefficient of friction to 0 25 to 0 3. Below are provided a small number of values showing approximate values of friction coefficients to be used for steel screw fastened connections.

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. The coefficient of static friction typically denoted as μ s is usually higher than the coefficient of kinetic friction.
