Next determine the points on the straight line FDG where radii drawn from A to the degree divisions on the arc would cross it, and carefully mark these crossings.
In the upper part of the front of the forearm the antecubital fossa or triangle is seen; its outer boundary is the brachio-radialis, its inner the pronator radii teres, and where these two join below is the apex.
And the measure of these angles is found by describing, about the point B, a circle which cuts the radii AB, BC.
The problem of constructing successive radii vectores, the angles of which are measured off from the radius vector of the body at the original given position, is then a geometric one, known as Kepler's problem.
This makes the Euphrates the main eastern limit, with radii to the north-east angle of the Levant and the south-east angle of the Black Sea, and roughly agrees with the popular conception of Asia Minor as a geographical region.
Although the longitude of the fictitious planet at the fictitious time is then equal to that of the true planet at the true time, their radii vectores will not be strictly equal.
The round part is smooth, but on both ends as it were there is a module from which on all sides there extend radii to the outer edge, which corresponds with the radii.
It is evident that the radii of the base-circles bear to each other the same proportions as the radii of the pitch-circles, and also that C1P1 = IC1 .
Hence, in any pair of circular wheels which work together, the numbers of teeth in a complete circumference are directly as the radii and inversely as the angular velocities.
In the wheel and axle, motion is received and transmitted by two cylindrical surfaces of different radii described about their common fixed axis of turning, their velocity-ratio being that of their radii.
The radii at the middle and end being thus determined, make the generating curve an arc either of a circle or of a parabola.
But a limit is put to the diminution of the radii of journals and pivots by the conditions of durability and of proper lubrication, and also by conditions of strength and stiffness.
Points of Concentration: For interior surfaces, the points of concentration may be placed in or near the radii of the area.
Inceptive Axes: For interior surfaces, the radii of the contour circle generally supply the axes of symmetry.
It constructs a triangular web, or net, usually composed of four radii crossed by a double elastic fiber.
Not that in all circles the radii are equal, but only that they are so in the circle ABC.
There exist no points without magnitude; no lines without breadth, nor perfectly straight; no circles with all their radii exactly equal, nor squares with all their angles perfectly right.
It is not true that a circle exists, or can be described, which has all its radii exactly equal.
B A is equal to C A, not because B C D is a circle, but because B C D is a figure with the radii equal.
In the diagram the construction is adapted to zones of 30° and the radii of the midzones found i.
The six equal radii of a snowflake, separating at equal angles, are measured beforehand by no knowledge; but it is the simple tendency of the original will, which so exhibits itself to knowledge when knowledge appears.
Light is thrown out on all sides from a luminous body like the spokes of a cart-wheel, and in the absence of any obstruction, the rays are distributed equally on all sides, diverging like the radii drawn from the centre of a circle.
By jumping over the light the radii projected from the candle over the sheet are crossed, and the shadow rises or falls as the figure passes upwards or downward.
Her eight long, slender, sensitive legs were outstretched and rested by their tips lightly on the bases of the taut radii so that they could feel the slightest disturbance in the web.
The foundation lines, the radii and a first set of circles are all made of lines without any sticky stuff on them.
In the center was the hub, her resting-place, whence the radii ran out, and where she had spun a broad zigzaggy band of white silk on which she stood or sat head downward.
The distance between the wheel centres is 32-1/2 inches; what are the radii of the respective pitch circles?
It will be observed then that the revolutions are in the same proportion as the numbers of the teeth or the radii of the wheels, or what is the same thing, in the same proportion as their diameters.
From this centre we mark the two arcs having radii corresponding to the unequal diameters of the pattern at the location where the chucking [V]'s are to be placed.
For curves outside pitch line use lower line of table; or, divideradii by any number and look under "faces.
To prove this we may show that the pitch radii of the two wheels are in the same proportion as their numbers of teeth, thus:-- Proof.
Take in succession asradii the chords A1, A2, A3, &c.
This is, in reality, a scale of centres or radii for different and various diameters of wheels and generating circles.
The only condition necessary to the construction of wheels of this class is that the sum of the radii of the pitch circles on the line of centres shall equal the distance between the axes of the two wheels.
A graphical presentation of the results may be made by laying off radii corresponding in position to those which divide the sectors in Fig.
Distances corresponding to the different percentages of frequency of the eight wind directions are then laid off along the eight radii of the circles, and the points thus fixed are joined by a line.
It is as in the circle, where the centre, remaining immovable in itself, nevertheless is the origin of all the radii originating there, and drawing their existence thence.
The radii by thus participating in the existence of the centre, the radii's principle, depend on what is indivisible, remaining attached thereto, though separating in every direction.
Norman soon kindled his torch, which now cast its red glare over the surface of the river, extending its fiery radii even to the banks on both sides of the stream.
Of course our young voyageurs followed the well-known practice of the country, and lay with their feet to the fire in such a manner that, when all were placed, their bodies formed four radii of a circle, of which the fire was the centre.
The radii of a circle are equal, because equality is involved in the very idea of the circle; consequently, if this be denied, it would be affirmed and denied at one and the same time.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "radii" in a variety of sentences. We hope that you will now be able to make sentences using this word.
