Required clutch torque capacity

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.

Calculates safety factor from clutch torque capacity and engine torque.

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.
