Required clutch clamp force

Calculates simplified clutch torque capacity from clamp force, friction coefficient, mean radius, and number of active friction interfaces.

Calculates average friction-surface pressure from clamp force and friction ring area; it is not maximum pressure or a pressure distribution.

Solves required friction coefficient for a target torque, clamp force, mean radius, and friction surface count.

Solves required clutch torque capacity from engine torque and safety factor.

Calculates friction ring area from outer and inner radius.

Calculates effective clutch friction radius for the uniform wear or uniform pressure assumption.
