A clutch coupling consist of plates squeezed between two shafts. The compressive force may be provided hydraulically or by a mechanical spring. In the latter case, the force may be adjusted by electro-magnetic action. The magnitude of the force determines the torque rating for the coupling: where F Spring Force, N Friction coefficient N Number of contact surfaces (one less than the number of plates) R Outer radius for the contact area, m r Inner radius for the contact area, m Some representative friction factors: Steel on dry steel 0.3 - 0.4 Steel on lubricated steel 0.06 - 0.1 Steel on cast iron 0.1 - 0.2 Steel on rubber 0.2 - 0.4 Rubber on rubber 0.4 - 0.6
