WebNow, find the value of the coefficient of friction between the particle and the plane. Solution: Frictional force, F = 5×g× sin30 (g is the acceleration due to gravity) Resolving perpendicular to the plane: Normal reaction Force, N = 5×g× cos30 In limiting equilibrium, F = N× μ 5gsin30 = 5gcos30 × μ μ = sin30/cos30 = 0.577 WebSep 1, 1992 · What's the coefficient of friction for concrete on concrete? The manufacturer of the units says it's 0.75, but that sounds high to me. The manufacturer's …
