Required clutch friction coefficient

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

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

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

Calculates friction ring area from outer and inner radius.

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

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