31. Its coefficient of friction is significantly lower than that of traditional UHMW, and greatly lower than nylon and acetal. 32. The plates provide a surface with a low coefficient of friction which can be attached to a supporting structure. 33. However, the coefficient of friction is not a function of mass or volume; it depends only on the material. 34. My assumption, on the other hand, is that the wall has the same coefficient of friction as the floor. 35. If the coefficient of friction on the ramps is low enough, then the lock ring can move on its own. 36. Whether a worm and gear is self-locking depends on the lead angle, the pressure angle, and the coefficient of friction . 37. Cadmium is used in many kinds of solder and bearing alloys, because a low coefficient of friction and fatigue resistance. 38. Physicists measure that sort of thing with a value they call the " coefficient of friction " ( COF ). 39. For example, silicone rubber or acrylic rubber-coated surfaces have a coefficient of friction that can be substantially larger than 1. 40. The coefficient of friction is an empirical measurement it has to be measured experimentally, and cannot be found through calculations.
