How to use Dynamometers in a sentence
The name has been applied generally to all kinds of instruments used in the measurement of a force, as for example electric dynamometers, but the term specially denotes apparatus used in connexion with the measurement of work, or in the measurement of the horse-power of engines and motors.
Apparatus is added to some dynamometers by means of which a curve showing the variations of P on a distance base is drawn automatically, the area of the diagram representing the work done; with others, integrating apparatus is combined, from which the work done during a given interval may be read off directly.
It is convenient to distinguish between absorption and transmission dynamometers.
The essential part of many transmission dynamometers is a spring whose deformation indirectly measures the magnitude of the force transmitted through it.
In spring dynamometers designed to measure a transmitted torque, the mechanical problem of ascertaining the change of form of the spring is complicated by the fact that the spring and the whole apparatus are rotating together.Advertisement
Initial studies examined strength in the lower extremities using isokinetic dynamometers.
The team is equipped with a total of eight engine dynamometers for the extensive bench testing that will be required.
