Motor density. No. of motors per filament versus attachment rate kA/kD for the motor speeds and external pressure denoted in the legend. The thick black dashed line has a slope of 3/2. Where data for the required P was not available, nmot was interpolated from runs with P slightly higher and lower than the target value.
