Examples of dynamometer in a Sentence
The fixed and suspended coils of the dynamometer are respectively connected in series with the magnetizing solenoid and with a secondary wound upon the specimen.
Using these buoys to guide the direction of tow, a grapnel, a species of fivepronged anchor, attached to a strong compound rope formed of strands of steel and manila, is lowered to the bottom and dragged at a slow speed, as it were ploughing a furrow in the sea bottom, in a line at right angles to the cable route, until the behaviour of the dynamometer shows that the cable is hooked.
The apparatus used to measure P or T is the dynamometer.
See also DYNAMOMETER for illustrations of the use of what are essentially friction-straps of different forms for the measurement of the brake horse-power of an engine or motor.
The useful residue, known as the "actual," "effective" or "brake" horse-power, can be directly measured by a dynamometer; it amounts to about 80% of the indicated horse-power for good condensing engines and about 85% for non-condensing engines, or perhaps a little more when the engines are of the largest sizes.
After everything had been got in readiness, careful observers were stationed along the track, and the machine was connected to a dynamometer.
The 2006 Group design Project, in partnership with Prodrive was to design a trailer dynamometer.
Rather, strength is determined with a hand-held dynamometer.
A fully instrumented dynamic dynamometer with rapid prototyping facilities is now fully operational and supporting this work.
A chassis dynamometer is used to measure the power transferred by the drive wheels onto the dynamometer's rollers.

The usual way of experimenting is to put a dynamometer car (see Dynamometer) between the engine and the train.
The weighing beam in the Hefner-Alteneck dynamometer is placed transversely to the belt (see Electrotechnischen Zeitschrift, 1881, 7).
In this case both the fixed and movable circuits consist of fine wires, and the instrument is constructed and used in a manner similar to the Siemens dynamometer employed for measuring continuous alternating current (see Amperemeter).
This corrected pull is then divided by the weight of the vehicles hauled, in which must be included the weight of the dynamometer car, and the quotient gives the resistance per ton of load hauled at a certain uniform speed on a straight and level road.
The best way of deducing r„ is to select portions of the dynamometer record where the speed is constant.
Morin's dynamometer is shown in fig.
