This arrangement permits of the roller being made to leave the trajectory in order that the carriage may be drawn back to a sufficient distance from the tool when the wheel is finished, so as to replace the latter by another.
When all was said and done, the only purpose for the existence of this magnificent machine was to put him where he was now; in the same trajectoryas the missile, and slightly behind it.
The cloud of fragments possessed the same trajectory as the missile originally had.
Even if it didn't burn up in the atmosphere, its trajectory would be too unpredictable.
Low-altitude satellites presented him with a serious problem, since there is not a whole lot of difference between the orbit of such a satellite and the trajectory of an ICBM.
Flat trajectory is impossible, because the instant the bullet leaves the rifle it is under the influence of gravity, and in traveling an inch even is depressed by it.
Whatever the trajectory may be we see that the shell must necessarily arrive in a slanting direction.
These considerations result in the naval gun needing to have as flat a trajectory as possible and its projectiles the highest possible speed.
We have established two facts, therefore, first, that the trajectory must be as flat as possible and, second, that to make it flat the velocity must be high.
Since the winds move clockwise around a "high," this gives a general northwesterly trajectory to the air currents in the vicinity of the Yucatan Peninsula.
This curved trajectory is undoubtedly one of the factors--but certainly not the only factor--contributing to the effect known as the "coastal hiatus.
An aeroplane travelling at a high speed, and pursuing an undulating or irregular trajectory is almost impossible to hit from the ground, as sighting is so extremely difficult.
Though the test was not particularly conclusive, and afforded no reliable data, one point was ascertained--the trail of smoke emitted by the shell enabled its trajectory to be followed with ease.
For a full description of the trajectory of bullets, see Shooting for Boys, by the present authors, and published by Moffat, Yard & Co.
It is highly probable that the trajectory of the ball is largely influenced by this period of contact.
He has come to the conclusion that "it is highly probable that the trajectory of the ball is largely influenced by this period of contact.
By this time the ball has arrived at the highest point of its trajectory and it then begins in the natural order of things to fall towards the earth.
This is, in fact, the ideal trajectory of a well-driven ball.
Determination of the relation of an arc of the trajectory to its projection.
The increase of the quantity of motion projected upon an axis or taken along the trajectory is equal to the impulsion of the projected resultant, or to that of the tangential force.
Hypothesis on the relation of the element of the trajectoryto its projection.
Influence of the wind upon the trajectory of the rocket.
Trajectory of the relative motions, relative velocities, and displacements upon curves or upon the direction of the mutual distance of the two points; use of the parallelogram to determine its amount.
The intersection of this conoid by a cylinder about the same axis is an orthogonal trajectory for a series of parallel sections.
Determination of the initial velocity and the angle of projection for a projectile which has to pass, firstly, through two given points; secondly, through one given point, the trajectory having at this point a known direction.
The acceleration along the trajectory is due to the tangential force.
Two rifles of different type may be equally accurate, but the accuracy of the one having the flatter trajectory will, naturally, be less affected by slight errors in sight setting.
The flatness of trajectory is dependent upon the muzzle velocity, and, to some extent, upon the form of the bullet.
Hence, we see that the rifle with the flatter trajectory is better.
Again, another advantage of the rifle with the flatter trajectory is that it holds more ground under its fire.
Its extent will, of course, depend on the height of the obstacle, the curvature of the trajectory and the slope of the ground in rear of the obstacles.
For example, take our service rifle: At a range of 500 yards, the bullet, at the highest point in its trajectory or line of flight, is 2 feet above the line of sight.
The gold spangles passing through his wings described a trajectory which was easily photographed.
The photographs of the trajectory of the wing of an insect are very interesting.
Nevertheless, Mr. Muybridge endeavored to develop from a series of images the trajectory of each leg of a horse, but the curves obtained in these laborious attempts had not sufficient precision.
The resistance to the air does the rest, namely, effects those changes in surface obliquity which determine the formation of an 8-shaped trajectory by the extremity of the wing.
A very simple method enables us to obtain, with perfect fidelity, the trajectory of a body in movement; it is the photographing of this body in front of a black surface.
These movements are equivalent to tiny currents, and the mobile electron, when animated with a considerable velocity, must be sensitive to the action of the magnet which modifies the form of the trajectory and the value of the period.
In the meantime the bullet was describing in the darkness that incalculable trajectory which no landmark allowed them to find out.
In fact, the trajectory of the projectile was between the earth and the moon.
The travellers were far from that central point which they ought to have touched if their trajectory had not suffered an irremediable deviation.
However slight it had been, it had been sufficient to modify the trajectory of the projectile.
The direction of the projectile towards the northern hemisphere proved that its trajectory had been slightly modified.
Every object thrown out of the projectile would follow the same trajectoryand only stop when it did.
Now the trajectory followed by the projectile dragged it precisely towards that mountainous region of the southern hemisphere where rise the finest specimens of lunar orography.
It is about the same trajectory that the bomb of a howitzer describes.
And, indeed, if certain of these bodies pass through our atmosphere at two or three leagues from the earth, others describe their trajectory at a distance the atmosphere cannot reach.
Because in the first case the distance from the center to any trajectory will remain constant; in the second case this will be the absolute value of the angle of each trajectory with the faces of the cuboid.
The trajectory of a gaseous molecule may be regarded as formed of straight segments united by very small arcs corresponding to the successive impacts.
Shall we conclude that the straight being by definition the trajectory of light does not satisfy the postulate, or, on the other hand, that the straight by definition satisfying the postulate, the ray of light is not straight?
All of them claimed to have seen it the same night, the same hour, the same minute, the same second, although the trajectory of the mysterious voyager took it but a moderate height above the horizon.
But in following this unchanging trajectory she was bearing due south, towards those polar regions which Robur had endeavored to avoid.
The trajectory controls of the projector were beside me.
The range-finder for the giant projector was here; its little telescope with the trajectory apparatus and the firing switch were unmistakable.
The animal is not the moving body of the mathematicians, the particle of matter guided in its trajectorysolely by the motive forces and the resistance of the medium traversed; it bears within itself conditions which control the others.
