Factors on which friction depends
WebFriction depends on the nature of surfaces in contact. For a given pair of surfaces, friction depends upon the state of smoothness of those surfaces. The force of friction is greater … WebThe frictional force between two bodies depends mainly on three factors: (I) the adhesion between body surfaces (ii) roughness of the surface (iii) deformation of bodies. What is the value of friction factor? f stands for the Darcy friction factor. Its value depends on the flow’s Reynolds number Re and on the pipe’s relative roughness / D.

WebA high coefficient of friction produces more friction. Normal force ( F_N F N ): squeezing surfaces together more tightly increases the friction. This is one reason why heavy … What are the factors affecting friction? 1. The smoothness of the sliding object. 2. The smoothness of the surface. 3. The force between the two bodies in the normal direction (perpendicular to the sliding direction) 4. Friction also depends on the design of an object. 5. Friction is independent of ... See more Smooth surfaces slide over surfaces easily compared to rough ones. One can notice the irregularities at the microscopic scale. These irregularities hinder the sliding between the … See more The force in the normal direction (perpendicular to the sliding plane) will increase the interaction between the surface thus increasing the friction. Friction is thus directly proportional to the normal force applied. … See more It is impossible to have perfectly smooth surfaces. Each surface will have its own roughness. This roughness combined with the roughness of the … See more
WebWhat are the factors affecting friction? Friction is basically dependent upon the nature of the body as well as on the pulling force. If the body is in rest and no pulling force is acting than the force of friction will be zero. The above image shows friction in different direction. Continue Reading José Esteves B. Rabello
