WebDefinition. Coefficient of friction (COF) is a unitless number that represents the resistance to sliding of two surfaces in contact with each other. These values should be between 0 and 1, with a higher value indicating more resistance to sliding. Static COF values are measured as two surfaces just begin to move against each other, and kinetic ... WebThe Euler-Eytelwein equation (1) relates the tension of the two ends of the rope: T 2 = T 1 e μθ, where T 2 is the tension in the rope due to the load it's supporting, T 1 is the tension necessary to hold the load without slipping, …
