A ray of light from a lamp is thrown on the mirror, whence it is reflected upon a white surface or scale set at a distance of about 3 ft., forming a bright spot on the surface; the slightest angular deflexion of the mirror, owing to its distance from the scale, moves the spot of light a very appreciable distance to the right or left according to the direction of the angular movement.
Its deflexion was observed by an attached mirror in the usual way.
The outer terminals of this junction are connected to a galvanometer, and when electric oscillations are sent through the fine wire they cause a deflexion of this galvanometer (fig.
At first a considerable current is indicated by the galvanometer; the deflexion soon diminishes, however, and finally becomes very small.
Taking disease to be a deflexion from the line of health, the first requisite of medicine is an extensive and intimate acquaintance with the norm of the body.
If the quadrants of an electrometer are con - nected to the ends of a non-inductive circuit in series with the power-absorbing circuit, and if the needle is connected to the end of this last circuit opposite to that at which the inductionless re - sistance is connected, then the deflexion of the electrometer will be proportional to the power taken up in the circuit, since it is pro - portional to the mean value of (A - B) IC - 1 (A ±B)}, where A and B are the potentials of the quadrants and C is that of the needle.
To take the example given under Confusions of Words above, loin for lion in Cranford is probably a printer's error, but it is conceivable that it is due to a deflexion of the authoress's mind or pen through the accidental proximity of the "mutton chop."
By the vibration experiment we obtain the value of the product of the magnetic moment (M) of the magnet into the horizontal component (H), while by the deflexion experiment we can deduce the value of the ratio of M to H, and hence the two combined give both M and H.
When conducting a deflexion experiment the de flecting magnet K is placed with its centre at 30 cm.
The value of the constants P and Q can be obtained by making deflexion experiments at three distances.
Thus it is usual, if the magnets are of similar shape, to make the deflected magnet 0.467 of the length of the deflecting magnet, in which case Q is negligible, and thus by means of deflexion experiments at two distances the value of P can be obtained.
Deflexion experiment, then no correction on account of the effect of temperature in the magnetic moment would be necessary in either experiment.
In the deflexion experiment, in addition to the induction correction, and that for the effect of temperature on the magnetic moment, a correction has to be applied for the effect of temperature on the length of the bar which supports the deflexion magnet.
157, since it caused a deflexion in the watercourse along the base of the Cronion constructed by Herodes Atticus.
Deflecting Force for Translation in a Curved Path.In machinery, deflecting force is supplied by the tenacity of some piece, such as a crank, which guides the deflected body in its curved path, and is unbalanced, being employed in producing deflexion, and not in balancing another force.
If there is the slightest displacement of the centre o gravity of the system from the axis of revolution a force acts on th shaft tending to deflect it, and varies as the deflexion and as th square of the speed.
The elastic resistance evoked by this deflexion is proportional to the deflexion, so that if c is a constant depending upon the form,, material and, method of support of the shaft, the following equality must hold if the shaft is to rotate stably at the stated speed- -~ (y+e)ai=cy, from which y=Wafe/(gcWa2).
Let a small body of the weight w undergo translation in a circulai path of the radius p, with the angular velocity of deflexion a, so that the common linear velocity of all its particles is v=ap. Then the actual energy of that body is WV2/2g = Waip2/2g.
