**angular**velocity as the sun.It is easily seen that if the mirror be rotated at the same

**angular**velocity as the sun the right ascensions will remain equal throughout the day, and therefore this device reflects the rays in the direction of the earth's axis; a second fixed mirror reflects them in any other fixed direction.By adjusting the right ascension of the plane ABC and rotating the axis with the

**angular**freedom of the telescope in right ascension, while its position at the lower end of a too weak polar axis tends to create instability from torsion of that axis.When the

**angular**momentum is too great for the usual spheroidal form to persist, this gives place to an ellipsoid with three unequal axes; this is succeeded by a pear-shaped form.As the simple star radiates heat and contracts, it retains its

**angular**velocity about the pole, in the direction of diminishing radius vector.The second general result is the Principle of

**Angular**Momentum.If extraneous forces act, the total

**angular**momentum about any fixed axis is in time t increased by the total extraneous impulse about that axis.If there are no extraneous forces, or if the extraneous forces have zero moment about any axis through G, the vector which represents the resultant

**angular**momentum relative to G is constant in every respect.On this basis we can predicate the principles of linear and

**angular**momentum, as in 15.If we integrate with respect to I between fixed limits, we obtain the principles of linear and

**angular**momentum in the form previously given, Hence, whichever form of postulate we adopt, we are led to the principles of linear and**angular**momentum, which form in fact the basis of all our subsequent work.Then dU/dt, =w say, is the

**angular**velocity of the body.The

**angular**momentum of a particle m at a distance r from the axis is mwr.The

**angular**velocity being constant, the effective force on a particle m at a distance r from Oz is snw2r toward& this axis, and its components are accordingly w2mx, wfmy, 0.If the extraneous forces have zero moment about G the

**angular**velocity 0 is constant.It may also be deduced from the principles of linear and

**angular**momentum as embodied in the equations (9).It is to be carefully noticed that the axis of resultant

**angular**momentum about 0 does not in general coincide with the instantaneous axis of rotation.The axis of resultant

**angular**momentum is therefore normal to the tangent plane at J, and does not coincide with OJ unless the latter be a principal axis.The motion of a rigid body in the most general case may be specified by means of the component velocities u, v, w of any point 0 of it which is taken as base, and the component

**angular**velocities p, q, r.The circle is described with the constant

**angular**velocity o.As an example of this latter type, suppose that a sphere is placed on the highest point of a fixed sphere and set spinning about the vertical diameter with the

**angular**velocity n; it will appear that under a certain condition the motion of G consequent on a slight disturbance will be oscillatory.The slightest frictional forcessuch as the resistance of the aireven if they act in lines through the centre of the rolling sphere, and so do not directly affect its

**angular**momentum, will cause the centre gradually to descend in an ever-widening spiral path.Now T = 3/41w1, where w is the

**angular**velocity and I is the moment of inertia about the instantaneous axis.Again, the vector which represents the

**angular**momentum with respect to 0 will be constant in every respect.The motion of the body relative to 0 is therefore completely represented if we imagine the momental ellipsoid at 0 to roll without sliding on a plane fixed in space, with an

**angular**velocity proportional at each instant to the radius-vector of the point of contact.If p, q, r be the component

**angular**velocities about the principal axes at 0, we have (Ap+B2q+C,2)/r = (Ap+Bq1+Cr2)/2T, (3) each side being in fact equal to unity.The

**angular**velocity (r) about this axis is then constant.For we have seen that r is constant when there are no extraneous forces; and r is evidently not affected by an instantaneous impulse which leaves the

**angular**momentum Cr, about the axis of symmetry, unaltered.The moving axes Ox, Oy, 01 form a rigid frame of reference whose motion at time t may be specified by the three component

**angular**velocities p, q, r.The components of

**angular**momentum about Ox, Qy, 01 will be denoted as usual by X, u, v.Hence the altered

**angular**momentum about Ox will be X+OX+(is+Ou)(rOt)+ (v+Oe)qOt.As a first application of the equations (2) take the case of a solid constrained to rotate with constant

**angular**velocity to about a fixed axis (1, m, n).The meaning of these quantities is easily recognized; thus X is the

**angular**momentum about a horizontal axis normal to the plane of 0, u is the**angular**momentum about the vertical OZ, and s is the**angular**momentum about the axis of symmetry..Let the

**angular**velocity of the rotation be denoted by a=dO/dt, then the linear velocity of any point A at the distance r from the axis is or; and the path of that point is a circle of the radius r described about the axis.Let -y denote the total

**angular**velocity of the rotation of the cone B about the instantaneous axis, $ its**angular**velocity about the axis OB relatively to the plane AOB, and a the**angular**velocity with which the plane AOB turns round the axis OA.It is required to find the ratios of those

**angular**velocities.Let V5 denote the velocity of advance at a given instant, which of course is common to all the particles of the body; a the

**angular**velocity of the rotation at the same instant; 2,r = 6.2832 nearly, the circumference of a circle of the radius unity.In the investigation, therefore, of the comparative motion, of the driver and follower, in an elementary combination, it is unnecessary to consider relations of

**angular**direction, which are already fixed by the connection of each piece with the frame; so that the inquiry is confined to the determination of the velocity ratio, and of tbe directional relation, so far only as it expresses the connection between forward and backward movements of the driver and follower.Application to a Pair of TurnIng Fseces.Let ai, a2 be the

**angular**velocities of a pair of turning pieces; Of, Oi the angles which their line of connection makes with their respective planes of rotation; Ti, r2 the common perpendiculars let fall from the line of connection upon the respective axes of rotation of the pieces.That the

**angular**velocities of a pair of turning pieces in rolling contact must be inversely as the perpendicular distances of any pair of points of contact from the respective axes.That the linear velocity of a shifting piece in rolling contact with a turning piece is equal to the product of the

**angular**velocity of the turning piece by the perpendicular distance from its axis to a pair of points of contact.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.Hence also, in any pair of circular wheels which rotate continuously for one revolution or more, the ratio of the numbers of teeth and its reciprocal the

**angular**velocity ratio must be expressible in whole numbers.The

**angular**velocity ratio due to the sliding contact of the teeth will be the same with that due to the rolling contact of the pitch-circles, if the line of connection of the teeth cuts the Ca line of centres at the pitchpoint.Thus the relative motion of the wheels is unchanged; but I is considered as fixed, and 2 has the total motion, that is, a rotation about the instantaneous axis I, with the

**angular**velocity cii+a1.The only modification required in the formulae is, that in equation (26) the difference of the

**angular**velocities should be substituted for their sum.Any other convenient figure may be assumed for the path of contact, and the corresponding forms of the teeth found by determining what curves a point T, moving along the assumed path of contact, will trace on two disks rotating round the centres of the wheels with

**angular**velocities bearing that relation to the component velocity of T along TI, which is given by Principle II.The

**angular**velocities of the screws are inversely as their numbers of threads.Coupling of Parallel AxesOldhams CouplingA coupling is a mode of connecting a pair of shafts so that they shall rotate in the same direction with the same mean

**angular**velocity.The

**angular**velocities of a pair of connected circular pulleys or drums are inversely as the effective radii.The axes of rotation of a pair of turning pieces connected by a link are almost always parallel, and perpendicular to the line of connection n which case the

**angular**velocity ratio at any instant is the recipocal of the ratio of the common perpendiculars let fall from the me of connection upon the respective axes of rotation.Coupling of Parallel Axes.Two or more parallel shafts (such as those of a locomotive engine, with two or more pairs of driving wheels) are made to rotate with constantly equal

**angular**velocities by having equal cranks, which are maintained parallel by a coupling-rod of such a length that the line of c000exion is equal to the distance between the axes.Let ai, a2, af be the

**angular**velocities of the first, intermediate, and last shaft in this train of two Hookes couplings.Then, from the principles of 60 it is evident that at each instant ai/ai = ai/aa, and consequently that ai; so that the fluctuations of

**angular**velocity ratio caused by the first coupling are exactly neutralized by the second, and the first and last shafts have equal**angular**velocities at each instant.Required the relation between the velocity of translation 02 of W and the

**angular**velocity af of the differential barrel.If dw/dt is the

**angular**acceleration of the link, dw/dt X CB is the tangential acceleration of the point B about the point C. Generally this tangential acceleration is unknown in magnitude, and it becomes part of the problem to find it.The principles of this reduction are that the ratio of the given to the equivalent force is the reciprocal of the ratio of the velocities of their points of application, and the ratio of the given to the equivalent couple is the reciprocal of the ratio of the

**angular**velocities of the pieces to which they are applied.When the relative motion of the rubbing surfaces is one of rotation, the work of friction in a unit of time, for a portion of the rubbing surfaces at a given distance from the axis of rotation, may be found by multiplying together the friction of that portion, its distance from the axis, and the

**angular**velocity.Its moment is found by multiplying the normal pressure between the rolling surfaces by an arm, whose length depends on the nature of the rolling surfaces, and the work lost in a unit of time in overcoming it is the product of its moment by the

**angular**velocity of the rolling surfaces relatively to each other.Neglecting the mass of the shaft itself, when the shaft rotates with an

**angular**velocity a, the centrifugal force Wae/g will act upon the shaft and cause its axis to deflect from the axis of rotation a distance, y say.In finding the position in which the bob will revolve with a given

**angular**velocity, a, for most practical cases connected with machinery the mass of the rod may be considered as insensible compared with that of the bob.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.The product wp/g, by which the half-square of the

**angular**velocity is multiplied, is called the moment of inertia of the revolving body.Flywheels.A flywheel is a rotating piece in a machine, generally shaped like a wheel (that is to say, consisting of a rim with spokes), and suited to store and restore energy by the periodical variations in its

**angular**velocity.The principles according to which variations of

**angular**velocity store and restore energy are the same as those of 117, only substituting moment of inertia for mass, and**angular**for linear velocity.The actual energy due to the rotation of the fly, with its mean

**angular**velocity, is equal to one-half of the periodical excess of energy multiplied by the steadiness.Let da be the deviation of

**angular**velocity to be produced in the interval dt, and I the moment of the inertia of the body about an axis through its centre of gravity; then 1/8Id(&) = Iada is the variation of the bodys actual energy.To find the

**angular**acceleration A, draw kI, bt respectively parallel to and at right angles to the link KB.Then tb represents the

**angular**acceleration of the point B relatively to the point K and hence tb/KB is the value of A, the**angular**acceleration of the link.His features were

**angular**and somewhat harsh, but with a striking face and very fine eyes of a brilliant dark blue.Large masses of granite are found in many parts of Sweden, in Kronoberg, Orebro, Goteborg, Stockholm, &c. Sometimes the granite graduates into gneiss; sometimes (as north of Stockholm) it encloses large

**angular**pieces of gneiss.The latter is less compact and contains

**angular**boulders, often of a considerable size, but no powder.The irritation of the conjunctiva caused by dust leads to winking of the eyelids, lachrymation and rubbing, which tend to remove it; but after the dust has been removed violent rubbing tends rather to keep up the irritation; and sometimes, if the particle of dust remains under the eyelid and is sharp and

**angular**, the process of rubbing may cause it to injure the conjunctiva much more than if it were left alone.They are large perennial climbers growing from short thick underground stems, from which rise numerous semi-woody flexuous

**angular**stems, bearing large alternate stalked long-persistent and prominently net-veined leaves, from the base of which spring the tendrils which support the plant.The basement storey has the same number of faces formed into convex flutes which are alternately

**angular**bottom of the tank, the electrolyte passes from the anode chamber to a series of tanks in which the more electro-negative constituents (silver, &c.) are chemically separated, and thence to the cathode chamber, where the copper is deposited electrolytically, thence it passes again to the anode chamber and so completes the cycle.These are often wedge-shaped and

**angular**; in some cases they consist of a short, thick stalk, terminating in a peltate expansion, or prolonged upwards in the form of a triangular lamina.A male flower consists of a single

**angular**perianth, through the open apex of which the flower-axis projects as a slender column terminating in two anthers.The equations of surfaces of equal

**angular**motion would be of the form r =R (i --6 cos 2 0), where e is proportional to the square of the**angular**motion, supposed small, and R increases as e diminishes.But this theory gives no clue to the results relating to hydrogen, which belongs to a high level, and which Adams has shown to move with an

**angular**velocity decidedly greater than the equatorial**angular**velocity below it, and not to show any sign of falling off towards the poles.Lines of lanthanum and carbon which are believed to belong to a low level showed systematically smaller

**angular**velocity than the average.Apart then from absorption there will be a discontinuous change in brightness in the apparent disk at that value of the

**angular**radius d which corresponds to tangential emission from the upper lever r' of this mirage-forming region.The greater µ is, the greater would be the value of d, the apparent

**angular**radius, corresponding to horizontal emission from a given level r, and that whether we accept Schmidt's theory or not.Better determinations of the actual value came from the heliometer, and gave an

**angular**.If M is the central mass, n the

**angular**velocity, and a the distance, the balance of the two forces is expressed by the equation an' =.1111a2, whence a 3 n 2 = M, a constant.It is an elementary principle of mechanics that this force varies directly as the product of the distance of the moving body from the centre of motion into the square of its

**angular**" matterhorns."Then, by an obvious law of kinematics, the

**angular**motion round the earth would be most rapid at the point nearest the earth, that is at perigee, and slowest at the point most distant from the earth, that is at apogee.Thus the apogee and perigee became two definite points of the orbit, indicated by the variations in the

**angular**motion of the moon.It is brittle, and when hammered readily breaks up into a powder of

**angular**grains.The object is then projected with such acute pencils on the plane focused for, in this case on the plane on which the eye can just accommodate itself, that the circle of confusion arising there is still so small that it is below the limit of

**angular**distance of a body from the pericentre of the orbit in which it is moving.The instrument can be provided with a curve or table showing the current corresponding to each

**angular**displacement of the torsion head.To do this the actual speed in the orbit, and in a yet higher degree the

**angular**speed around F, must be greatest at pericentre, and continually diminish till the apocentre is reached.From the law of

**angular**motion of the latter its radius vector will run ahead of PQ near A, PQ will overtake and pass it at apocentre, and the two will again coincide at pericentre when the revolution is completed.Instead of the period it is common in astronomical practice to use the mean

**angular**speed, called the mean motion of the body.This is defined as the speed of revolution of the fictitious body already described, revolving with a uniform

**angular**motion and the same periodic time as the planet.The angle from the pericentre to the actual radius vector, and the length of the latter being found, the
