Now a dynamometer is an instrument for measuring the force of a "pull," and when we call it self-recording we mean that it automatically takes a record of a series of pulls or of a varying pull.
If a model behaves badly in the tank the fault may be either too much wave making or too much eddy making, and which of these it is the dynamometerdoes not of course tell.

The front wheel is capable of turning freely in the horizontal plane, and the dynamometer is mounted upon a frame provided with a screw that permits of regulating its position according to the slope of the ground.
The method of suspension of the dynamometer allows it to take automatically the inclination of the line of traction without any torsion of the plates.
This type differs from the dynamometer movement in that a vane of very soft iron replaces the moving coil.
In the construction of a dynamometer what material should not be used and why?
The dynamometer movement is, for any indication, more accurate than the magnetic vane, but cannot readily be employed for the indication of current, as required in ammeters.
The general appearance of the dynamometer movement and the relative positions of the various parts are clearly shown.
In preparation for a third run, in which it was intended to use full power, a dynamometer was attached to the machine and the engines were started at 200 lbs.
After the dynamometer test had been completed, and everything had been made ready for trial in motion, careful observers were stationed on each side of the track, and the order was given to release the machine.
After passing several times round the drum, so as to get a good hold of it, the cable passes through the dynamometer to the sheave or grooved pulley projecting from the stern, and from thence it passes to the water.
At the outer end of the derrick, the dynamometer and a fourteen-inch block were attached.
A very heavy strain was imposed on the wire as the vessel rose in the swell; the dynamometerregistering up to seven tons.
Then, as if determined to make a certainty of his condition, he took a dynamometer from one of the drawers in his old veneered bureau.

The dynamometer is now more powerful in absorbing work than in the form Fig.
To put it in another way, the errors in the use of dynamometer are due to the vibration of the spring which measures P, and are caused by variations of the coefficient of friction of the dynamometer.
Consequently, in a dynamometer in this simple form more or less violent oscillations of the weights are set up, which cannot be directly controlled without impairing the accuracy of the dynamometer.
As this larger dynamometer has already been described, it is only necessary to add that the small one consisted of twelve rotating plates and twelve stator plates twelve inches in diameter.
