Vorac. 660 1 6 17. 2. The frictional force is proportional to the real, not apparent, area of contact, and the real area of contact is proportional to the load. Therefore the area cancels and the frictional force is proportional to the load. – John Rennie.

Webof friction because the lubricant layer not only greatly reduces the coefficient of friction but also reduces the surface damage caused by the asperities rubbing together. For partial lubrication the coefficient of friction is generally between 0.01 and 0.1, and for fully hydrodynamic lubrication this is further reduced to between 0.001 and 0.01. Web2. Influence of Temperature on Friction Coefficient. The state change of molecule motion of high polymer is called laxation according to the view of dynamics. The rising of temperature can improve heat movement ability of moving units on the one hand. On the other hand, because of thermal expansion, it increases molecule distance.
