The Prony brake is a simple type of dynamometer used to measure the amount of torque produced by a motor or engine in order to determine its brake horsepower rating.

Â­In a trÂ­aditional braking system, brake pads produce friction with the brake rotors to slow or stop the vehicle. Additional friction is produced between the slowed wheels and the surface of the road. This friction is what turns the car's kinetic energy into heat.In a trÂ­aditional braking system, brake pads produce friction with the brake rotors to slow or stop the vehicle.
