Static friction coefficient values
WebStatic friction is the friction force between two surfaces at rest relative to each other. It is the friction that exists between the contacting surfaces of static objects. The static friction force must be overcome by the applied force before an object can move. Once the object is set in motion, kinetic friction takes over. For instance; WebMost polymers have coefficients of friction in the range 0.2 to 0.6 but the fluorocarbons generally have lower coefficients of friction than this range. PTFE has the lowest recorded m value for any material with a dynamic coefficient of friction of between 0.05 and 0.15 and a static coefficient of friction of approximately 0.05.

WebIf the coefficient of static friction is 0.45, you would have to exert a force parallel to the floor greater than f s (max) = μ s N = ( 0.45) ( 980 N) = 440 N to move the crate. Once there is motion, friction is less and the coefficient of kinetic friction might be 0.30, so that a force of only 290 N f k = μ k N = ( 0.30) ( 980 N) = 290 N WebThe coefficient of static friction between the crate and floor is 0.700 and the coefficient of kinetic friction is 0.600. A horizontal force →P is applied to the crate. Find the force of friction if (a) →P = 20.0Nˆi, (b) →P = 30.0Nˆi, (c) →P = 120.0Nˆi, and (d) →P = 180.0Nˆi.
