# W Sentence Examples

Let this number be denoted by (

**w**; 0, n).In order to obtain the seminvari ants we would write down the (

**w**; 0, n) terms each associated with a literal coefficient; if we now operate with 52 we obtain a linear function of (**w**- I; 8, n) products, for the vanishing of which the literal coefficients must satisfy (**w**-I; 0, n) linear equations; hence (**w**; 8, n)-(**w**-I; 0, n) of these coefficients may be assumed arbitrarily, and the number of linearly independent solutions of 52=o, of the given degree and weight, is precisely (**w**; 8, n) - (**w**- I; 0, n).It is shown in the article on Combinatorial Analysis that (

**W**and B, it is, nevertheless, the case that by making the index e =1.6, and assigning a suitable value to r t, a formula may be obtained giving an approximation to the truth which is sufficiently close for the ordinary purposes of electrical engineers, especially when the limiting value of B is neither very great nor very small.Working with two different specimens, he found that the hysteresis loss in ergs per cubic centimetre (

**W**) was fairly represented by o 00125B 1 6 and o o0101B 1 ' 6 respectively, the maximum induction ranging from about 300 to 3000.After pointing out that, since the magnetization of the metal is the quantity really concerned,

**W**" on either side of Cape Helles at the south-western end, and " X " and " Y " on the outer shore; " V " and "**W**" were regarded as of primary importance, as those two beaches offered suitable landing places from the point of view of subsequent operations.The attacks at " S " and " Y " were intended to be subsidiary; but great importance was attached to that at " X " owing to the vicinity of this point to "

**W**."As it turned out, the actual disembarkations at " S," " X " and " Y " were carried out without any very great difficulty; but the troops detailed for "

**W**" beach only gained a footing after incurring very heavy losses and by a display of indomitable resolution, while at " V " the operation went very near to failing altogether.But the forces which had landed at "

**W**" and " X " beaches had joined hands, the one battalion detailed for " S " beach had secured a good position, and during the night the troops still left aboard the " River Clyde " contrived to disembark.What was left of the force originally detailed for the landing at " V " beach contrived during the early hours by stern fighting to occupy some high ground hard by, and also to join hands with the troops landed at "

**W**, done by the body in expanding or otherwise, which can be utilized for mechanical purposes, and ceases to exist as heat in the body.This equation is generally true for any series of transformations, provided that we regard H and

**W**as representing the algebraic sums of all the quantities of heat supplied to, and of work done by the body, heat taken from the body or work done on the body being reckoned negative in the summation.The area ABCD, representing the work,

**W**, per cycle, is the difference (H' - H") of the quantities of heat absorbed and rejected at the temperatures 0 and 0".As the temperature 0" is lowered, the area of the cycle increases, but since

**W**can never exceed H', there must be a zero limit of temperature at which the pressure would vanish and the area of the cycle become equal to the whole heat absorbed at the higher temperature.The change of the intrinsic energy in passing from one state to another, as from B to C is represented by the addition of the heat-area H= Bczz', and the subtraction of the work-area

**W**= BCcb.The same result follows if the work

**W**=RT log e ?'Joule's experiments on the equivalence of

**W**and H were not sufficiently precise to decide the question.This most fundamental point was finally settled by a more delicate test, devised by Lord Kelvin, and carried out in conjunction with Joule (1854), which showed that the fundamental assumption

**W**=H in isothermal expansion was very nearly true for permanent gases, and that F'(t) must therefore vary very nearly as J/T.Combining this with the first law, for a Carnot cycle of finite range, if H is the heat taken in at 0', and H" is the heat rejected at 0", the work

**W**done in the cycle is equal to the difference H' - H", and we have the simple relations,**W**/(0' - o") =H'/o' =H" o".Then by relations (2) the heat, H, absorbed in the isothermal change BC, is to the work,

**W**, done in the cycle ABCD in the ratio of o to (o' - o").**W**, External work done by fluid.In this alphabet the Greek letter p (or rather a very similar letter with the loop a little lower down) is used to represent sh, and there are some peculiarities in the use of o apparently connected with the expression of the sounds h and

**w**.Calling the weight of the empty vessel

**w**, when filled with the liquid**W**, and when filled with the standard substance**W**l, it is obvious that**W**-**w**, and W1 -**w**, are the weights of equal volumes of the liquid and standard, and hence the relative density is (**W**-**w**)/(Wi -**w**).It is readily seen that

**W**+**W**i -**W**2 is the weight of the liquid displaced by the solid, and therefore is the weight of an equal volume of liquid; hence the relative density is**W**/(**W**+Wi - W2).If

**W**be the weight in air, and**W**, the weight in water, then**W**, is always less than**W**, the difference**W**- W1 representing the weight of the water displaced, i.e.Hence

**W**/(**W**-**W**,) is the relative density or specific gravity of the body.The principle is readily adapted to the determination of the relative densities of two liquids, for it is obvious that if

**W**be the weight of a solid body in air,**W**, and W2 its weights when immersed in the liquids, then**W**-**W**, and**W**-**W**2 are the weights of equal volumes of the liquids, and therefore the relative density is the quotient (**W**-**W**,)/(**W**- W2).If

**W**be the weight of the experimental solid in air,**w**the weight of the sinker in water, and**W**, the weight of the solid plus sinker in water, then the relative density is given by**W**/(**W**+**w**- Wi).There are several corrections of the formula O =

**W**/(**W**- W1) necessary to the accurate expression of the density.Less accurate formulae are =p

**W**/(**W**-**W**2), the factor involving the density of the air, and the coefficient of the expansion of the solid being disregarded, and 0 =**W**/(**W**-**W**1), in which the density of water is taken as unity.The counterpoise

**W**y llie,' and van Manen.The heating at the surfaces, the variations in their smoothness, and the variations of the lubrication make continuously variable, and necessitate frequent adjustment of

**W**or of the nuts.A flexible steel band, lined with wood blocks, is gripped on the motor fly-wheel or pulley by a screw A, which, together with

**W**, is adjusted to hold the brake steady.The external forces holding the brake from turning are

**W**, distant R from the axis, and the reaction,**W**1 say, of the lever against the fixed pin P, distant R1 from the axis.The moment of

**W**1 may be positive or negative.When the wheel is turning in the direction indicated, the forces holding the band still are

**W**, and p, the observed pull on the spring balance.Both these forces usually act at the same radius R, the distance from the axis to the centre line of the rope, in which case the torque T is (

**W**-p)R, and consequently the brake horse-power is (**W**- p)RX21rN, When µ 33,000 changes the weight**W**rises or falls against the action of the spring balance until a stable condition of running is obtained.The ratio

**W**/p increases very rapidly as 0 is increased,, and therefore, by making 0 sufficiently large, p may conveniently be made a small fraction of**W**, thereby rendering errors of observation of the spring balance negligible.Weights

**W**and**w**are adjusted to the torque.The number of molecules of the first kind of gas, whose components of velocity lie within the ranges between u and u+du, v and v+dv,

**w**and**w**+dw, will, by formula (5), be v?l (h 3 m 3 /7 3)e hm (u2+v2+w2)dudvdw (9) per unit volume.Thus the contribution to the total impulsive pressure exerted on the area dS in time dt from this cause is mu X udtdS X (11 3 m 3 /,r 3)e hm (u2+v2+w2 )dudvdw (I o) The total pressure exerted in bringing the centres of gravity of all the colliding molecules to rest normally to the boundary is obtained by first integrating this expression with respect to u, v,

**w**, the limits being all values for which collisions are possible (namely from - co too for u, and from - oo to + oo for v and**w**), and then summing for all kinds of molecules in the gas.The aggregate amount of these pressures is clearly the sum of the momenta, normal to the boundary, of all molecules which have left dS within a time dt, and this will be given by expression (pp), integrated with respect to u from o to and with respect to v and

**w**from - oo to +oo, and then summed for all kinds of molecules in the gas.The shunt coil Sh and the series coil Se are connected together at one point, and the remaining terminals of the dynamo and shunt coil must be connected to a " good earth," which is generally the gas or water pipes

**w**the small increase of pressure, and - (dy/dx) the volume decrease, then E=e/(- dy/dx) or**w**Ã†= - dy/dx (I) This gives the relation between pressure excess and displacement.Let us seek a more'exact value for

**w**, and let U be the velocity of sound in still air.Then the n waves occupy a space U +

**w**- u.If he were at rest, it would be the waves in length U +

**w**, for the wave passing him at the beginning of a second would be so far distant at the end of the second.But through his motion v in the second, he receives only the waves in distance U +

**w**- v.Since there are n waves in distance U +

**w**- u the number he actually receives is n(U +**w**- v)/(U +**w**- u).It is therefore

**W**m = (E 1 U) 27rUa/A = 27rnpUa.If

**w**'?If

**w**is the weight of a locomotive in tons, r the radius of curvature of the track, v the velocity in feet per sec.; then the horizontal force exerted on the bridge is wv 2 /gr tons.Let

**W**1 be the total live load, Wf the total flooring load on a bridge of span 1, both being considered for the present purpose to be uniform per ft.Since in designing a bridge W1-l-Wt is known, k(W1+Wf) can be found from a provisional design in which the weight

**W**2 is neglected.Let

**w**1,**w**2 be the weights of main girders per ft.Now let w1',

**w**3 = (**w**l +**w**2)1 2 /(Cds-1 2) = (**w**i -Fw 2)lr/ (Cs -lr), where C is a constant for any type of girder.Hence the formula is more useful in the form

**w**= (**w**i +w2)1 2 / (Kd -1 2) = (wl +**w**2)lr/ (K -lr) where k= (wl+w2-1-w3)lr/w3 is to be deduced from the data of some bridge previously designed with the same working stresses.That at the left abutment is R 1 =

**W**1.Till

**W**1 has advanced a distance a only one load is on the girder, and the curve A"F gives bending moments due to**W**1 only; as W1 advances to a distance a+b, two loads are on the girder, and the curve FG gives moments due to**W**1 and W2.Let

**w**e be the load per ft.Then

**w**e may be termed the uniform load per ft.But it is not difficult to find

**w**e, approximately enough for practical purposes, very simply.From these equations a value of

**W**e can be obtained.Hence the moment of the load on Am at C is wy0m, and the moment of a uniform load over any portion of the girder is

**w**is the locus of a system of null-lines meeting in a point, called the null-point of c. If a plane revolve about a fixed straight line p in it, its ntill-point describes another straight line p, which is called the conjugate line of p. We have seen that the wrench may be replaced by two forces, one of which may act in any arbitrary line p. It is now evident that the second force must act in the conjugate line p, since every line meeting p, p is a null-line.As a simple example, take the case of a light frame, whose bars form the slides of a rhombus ABCD with the diagonal BD, suspended from A and carrying a weight

**w**is the angular velocity and I is the moment of inertia about the instantaneous axis.Since

**w**varies as p, it follows that OH is constant, and the tangent plane at J is therefore fixed in space.When, in any problem, the values of u, v,
