A chassis dynamometer, informally referred to as a rolling road [1] or a dyno, is a mechanical device that uses one or more fixed roller assemblies to simulate different road conditions within a controlled environment, and is used for a wide variety of vehicle testing and development purposes. All Wheel Drive Chassis Dynamometer
Inertia sweep: an inertia dyno system provides a fixed inertial mass flywheel and computes the power required to accelerate the flywheel (the load) from the starting to the ending RPM. The actual rotational mass of the engine (or engine and vehicle in the case of a chassis dyno) is not known, and the variability of even the mass of the tires ...
A dyno torch, dynamo torch, or squeeze flashlight is a flashlight or pocket torch which generates energy via a flywheel. The user repeatedly squeezes a handle to spin a flywheel inside the flashlight, attached to a small generator/dynamo , supplying electric current to an incandescent bulb or light-emitting diode .
Prony brake dynamometers at a tractor contest in 1910 Schematic of a Prony brake Actual Prony Brake built for testing 5HP Steam Engine. The Prony brake is a simple device invented by Gaspard de Prony in 1821 to measure the torque produced by an engine.
Out-of-balance inertia forces in the wheel can cause different vertical oscillations depending on the track stiffness. Slipping tests done over greased sections of track showed, in one case, slight marking of the rail at a slipping speed of 165 mph but on softer track severe rail damage at 105 mph. [ 30 ]
Weighing 1,350 lb (610 kg), with a 525–550 hp (391–410 kW) iron block and head engine positioned near the car's polar moment of inertia for responsive turn pivoting, a Hewland 5-speed magnesium transaxle, and 10 in (254.0 mm) wide 13 in (330.2 mm) front/20 in (508.0 mm) wide 15 in (381.0 mm) rear magnesium wheels, it produced incredibly ...

The switched reluctance motor (SRM) is a type of reluctance motor. Unlike brushed DC motors , power is delivered to windings in the stator (case) rather than the rotor . This simplifies mechanical design because power does not have to be delivered to the moving rotor, which eliminates the need for a commutator .
