A Bicycle Ergometer with an Electric Brake

Introduces the bicycle ergometer with electric brake, describes its mechanical construction, and explains the method of calorimetric calibration.

Reports extensive calorimetric calibration experiments with both ergometers, measuring heat production per pedal revolution at varying speeds and currents.

Analyses eddy currents in the rotating copper disk using bismuth spiral measurements, then applies findings to principles for designing efficient electric brakes.
