# Belt or Rope Friction Equation & Calculator

## Capstan or Eytelwin Equation Calculation

Thold - Resulting force at other side (N)
µ -Coefficient of friction between rope & capstan
φ - Total rope angles (radians)

Capstan or Belt Friction calculator - equation & step by step calculation to find the belt friction on the rotating drum or capston or winch. Tlold = Thold x eTμΦ. Resulting force on the other side Thold; in Newton, coefficient of friction force between rope & capston material & total rope angle Φ in radians are the key terms of this calculation. The belt or rope frictional force changes due to coefficient, tension in the rope & total angle of contact. This can be easily determined by the capston or eytelwin equation.
