Give the classification of dynamometer. State the function of it.
Function of dynamometer: A dynamometer is a brake but in addition it has a device to measure the frictional resistance. Knowing the frictional resistance, we may obtain the torque transmitted and hence the power of the engine.
Absorption type dynamometers:
1. Prony brake dynamometer, and 2. Rope brake dynamometer.
Transmission type dynamometers
1. Epicyclic-train dynamometer, 2. Belt transmission dynamometer, and 3. Torsion dynamometer.
