Strength of clutch.

Range: [0,inf)Unit: torque * time = mass * (length^2) / time


The clutch is the mechanism that couples the engine to the wheels. A stronger clutch more strongly couples the engine to the wheels, while a clutch of strength zero completely decouples the engine from the wheels. Stronger clutches more quickly bring the wheels and engine into equilibrium, while weaker clutches take longer, resulting in periods of clutch slip and delays in power transmission from the engine to the wheels. The torque generated by the clutch is proportional to the clutch strength and the velocity difference between the engine’s rotational speed and the rotational speed of the driven wheels after accounting for the gear ratio. The torque at the clutch is applied negatively to the engine and positively to the driven wheels.
