Coefficient Of Friction Of Aluminum With Granite

F f frictional force n lb.

Coefficient of friction of aluminum with granite. N normal force between the surfaces n lb there are at least two types of friction forces. 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. From different studies it is revealed that various field process wear parameters influencing wear coefficient of friction of amc s. The friction force is the force exerted by a surface when an object moves across it or makes an effort to move across it.

For example static friction can prevent an object from sliding down a sloped surface. The coefficients of friction are independent of the surface area in contact. The coefficient of kinetic friction is generally lower than the coefficient of static friction on the same surface. Static friction is friction between two or more solid objects that are not moving relative to each other.

F f μ n 1. Coefficient of friction to 0 25 to 0 3. μ static μ s or kinetic μ k frictional coefficient. First you tape the low g accelerometer on the end of the surface in this case a slab of granite.

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. The coefficient of static friction typically denoted as μ s is usually higher than the coefficient of kinetic friction. The frictional force can be expressed as.
