The moment of the weight or its tendency to fall increases directly as the sine of the arc of rotation, while the torsional resistance increases as the arc, and for small angles the sine and the arc are practically equal.
It is assumed that the torsionalrigidity of the wire is diminished by an elevation of temperature, as the writer of this article had found it to be for copper, iron, platinum and other metals.
The question can be tested by observation of the torsional elasticity of thin fibres or wires.
The stress-couples consist of two flexural couples in the two principal planes, and the torsional couple about the tangent to the central-line.
After this the whole frame was tested against torsional strains, such as would be caused by the wind twisting one set of wings more than the other.
The means for preventing these torsional strains in the case of the models, when “overhead” type of launching car was used, has been described in Chapter X of Part I.
When used in the tests these heavier shafts, while much stronger, still showed a large amount of heating due to the fluctuating torsional strains.
Defn: Of or pertaining to torsion; resulting from torsion, or the force with which a thread or wire returns to a state of rest after having been twisted round its axis; as, torsional force.
An instrument for measuring rigidity by thetorsional oscillations of a weighted wire.
This torsional strain, added to the fact that the leg is perfectly straight, has led to the idea that a great deal of the weight is on the right leg.
There is thus no torsional or twisting strain on the shaft as there is at present with every golf club, and, as I have already shown, this torsional strain cannot be considered as a negligible factor in a club.
In the one case it is a physical cause, namely, the stiffness and torsional strain on the right leg, and in the other case it is a visual deception.
So long as the wire (supposed isotropic) is free from torsional stress, there will be no external evidence of magnetism.
To find the necessary diameter of shaft from a given torsional stress.
The rib A'' which is introduced to strengthen the shears against torsional strains, extends the full length of the shears.
Then the diameters of the two being such as to have equal torsional strength, we have-- 1st.
B, because in that case the action of the torsional pressure or twist is to lift the screw-driver out of the slot.
It’s like bothering about who wrote Shakespeare’s plays.
She might be an infant in the eyes of this accomplished flirt, but she had imagination and a brain capable under stress of abnormal rapidity of action.
The usual form of lathe and planer beds or frames is two side plates and a lot of cross girts; their duty is to guide the carriages or tables in straight lines and carry loads resisting bending and torsional strains.
Not only are the wheels subjected to very severe torsional strains, but the temperature at the circumference is raised very high in consequence of the friction.
The Method of Torsional Balance enables us to compare the excitatory efficiencies of two different stimuli which act simultaneously on the two flanks of the organ.
Having thus established the laws that guide torsional response, I shall try to explain certain related phenomena which are regarded as highly obscure.
The arrangement for obtaining record of the torsional response under a-position is shown in figure 179.
I shall, however, describe my investigations on the complicated torsional movements exhibited by certain leaflets by the action of vertical light.
The end of the aluminium wire is attached to the short arm of a recording lever; there is thus a compound magnification of the torsional movement.
The first part of the curve is the record of geotropic torsional movement.
Friction and the effect of weight is thus practically eliminated; the looped support prevented up or down movements, and yet allowed perfect freedom for torsional response.
Under normal conditions, the torsional response under light places the upper surface of the leaf or leaflets at right angles to light.
Variation of turgor can only cause a swing to and fro, in a direction perpendicular to the plane which divides the pulvinus into upper and lower halves; it can in no way induce a torsional movement, or a variation of the rate of that movement.
The torsional stresses act along ed, and in order to resist these stresses the shell must be so designed that the resisting ability will be increased along that line, re-acting along de.
By the stimulus of a blow there is produced a torsional vibration--a response followed by recovery.
The handle, by which a torsional vibration is imparted to the wire, may be slipped over either electrode.
Having done this, I applied to the same stalk two successive torsionalvibrations of 45° and 67° respectively.
By means of handles H H', torsional vibration may be imparted to either the end A or end B of the plant.
On now stimulating the wire as a whole by, say, torsional vibration, the current of response will be found towards the more excitable, i.
So also with the torsional vibrations of plants, I find response depending on the quickness with which the vibration is effected.
If now a rapid torsional vibration be given to A or B, an E.
I find that torsional vibration affords another very effective method of stimulation (fig.
I took a stalk, and, using the block method, with torsional vibration as the stimulus, obtained strong responses at both ends A and B.
On exciting the stem by taps ortorsional vibration, a responsive current was observed which flowed inwards from the more disturbed outer surface to the shielded core inside (fig.
I took a leaf-stalk of turnip and fixed it in the torsional vibrator.
These successive responses to taps and torsional vibrations are given in fig.
Such models are also strong, and able to withstand the torsionalstrain required by the rubber which is used for exerting the power.
It is so constructed that it must withstand an extraordinary torsional strain, being located at the forward portion of the wing surface.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "torsional" in a variety of sentences. We hope that you will now be able to make sentences using this word.
