What Is the Coefficient of Static Friction?
The static friction coefficient refers to that the magnitude of the maximum static friction force is directly proportional to the positive pressure between the contact surfaces and has nothing to do with the size of the contact surface. Its direction is opposite to the direction of the movement trend. The proportional coefficient is called the static friction coefficient. [1]

- 1. Test of static friction coefficient The so-called static friction coefficient generally refers to the maximum static friction coefficient, that is, the hoisting system is in a static state. Under the action of the maximum actual static tension difference, the friction coefficient between the wire rope and the liner.
- 2. Static friction coefficient Generally, the static friction coefficient refers to the ratio of the tangential force and the normal load required for the friction pair to start sliding. Ultra-precision machining has entered the nanoscale, which is called nanomachining.
- 3. CO is divided into two types: static friction coefficient and dynamic friction coefficient. Static friction coefficient refers to the force required during the initial movement, and dynamic friction coefficient refers to the force required for continuous movement. The COF referred to in this article refers to the dynamic friction coefficient.
- 4. When the brake drum and brake belt can rotate relative to each other before the brake is stepped on, the tire is still decelerating and rolling forward on the road. At this moment, the friction between the contact point of the tire and the ground is the static friction and its friction coefficient (also called the adhesion coefficient).

- 5. The ratio of force to positive pressure is called the static friction coefficient. The other is dynamic friction. When two contacting objects have started and continue to move relative to each other, there is dynamic friction between the contact surfaces. The ratio of this force to the positive pressure is called dynamic friction coefficient. Its value is slightly lower than the coefficient of static friction
