Clutch Brake Design: disc_brake
Clutch and brake design parameters — friction coefficients (dynamic and static), maximum pressure, temperature limits, sliding velocity, PV limits, and energy density for 9 device types (disc clutch, cone clutch, band brake, disc brake, drum brake, centrifugal clutch, electromagnetic clutch, hydraulic clutch, overrunning clutch) across 5 friction materials (organic, sintered metallic, cerametallic, carbon-carbon, paper wet). Includes design equation references.
