WebFigure 3: Plot of frictional force versus applied force Table 1 lists the coefficients of static and kinetic friction for various object/surface combinations [5, 8]. The coefficient of static friction is less than that of kinetic friction for all cases in the table except Teflon on Teflon. Table 1: Coefficients of static and kinetic friction WebThe frictional force for Static Friction can be expressed as: F max = μ F n where F max = Frictional force (N, lb) μ = static (μ s ) or kinetic (μ k ) frictional coefficient F n = Applied …
WebThe value of the coefficient of friction for a case of one or more bricks sliding on a clean wooden table is about 0.5, which implies that a force equal to half the weight of the bricks is required just to overcome friction in keeping the bricks moving along at a constant speed. WebUsing this, we can calculate the force of friction as follows: F = μN F = μ mg Substituting the values in the equation, we get F = (0.400) (40.0 kg) (9.80 m/s 2) F = 156.8 N The …
