Clutch friction ring area

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

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

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

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

Solves the exact and minimum integer number of active friction interfaces required to transmit a target torque.

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