Friction angle vs friction coefficient

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. WebMar 12, 2006 · 3.1 The coefficient of friction is the ratio of the fricti onal force resisting movement of the surface being tested to the force applied normal to that surface (the weight of the material above that surface). For the inclined plane, the coefficient is numerically equal to the tangent of the angle of incline.
