**tensions**of the band at the two ends of the elementary arc, or dT =dF =fTdO; which equation, being integrated throughout the entire arc of contact, gives the following formulae: - For if in the triangle abc the side ab is taken so as to represent on a given scale the tension of the surface of contact of the fluids a and b, and if the other sides be and ca are taken so as to represent on the same scale the
**tensions**of the surfaces between b and c and between c and a respectively, then the condition of equilibrium at 0 for the corresponding**tensions**R, P and Q is that the angle ROP shall be the supplement of abc, POQ of bca, and, therefore, QOR of cab. - When three films of the same liquid meet, their

**tensions**is greater than the sum of the other two, the drop will assume the form of a lens, the angles which the upper and lower surfaces of the lens make with the free surface of A and with each other being equal to the external angles of the triangle of forces. - But when the surface-tension of A exceeds the sum of the
**tensions**of the surfaces of contact of B with air and with A, it is impossible to construct the triangle of forces, so that equilibrium becomes impossible. - The edge of the drop is drawn out by the surface-tension of A with a force greater than the sum of the
**tensions**of the two surfaces of the drop. The drop, therefore, spreads itself out, with great velocity, over the surface of A till it covers an enormous area, and is reduced to such extreme tenuity that it is not probable that it retains the same properties of surface-tension which it has in a large mass. - If a and b are the two fluids and c the solid then the equilibrium of the
**tensions**at the point 0 depends only on that of thin components parallel to the surface, because the surface-**tensions**normal to the surface are balanced by the resistance of the solid. - As an experiment on the angle of contact only gives us the difference of the surface-
**tensions**at the solid surface, we cannot determine their actual value. - If the tension of the surface between the solid and one of the fluids exceeds the sum of the other two
**tensions**, the point of contact will not be in equilibrium, but will be dragged towards the side on which the tension is greatest. - (48) ° and in general the functions 0, or 4), must be regarded as capable of assuming different forms.

**tensions**for three fluids, which we may denote by T12, T23, T31. - If the above-mentioned condition be not satisfied, the triangle is imaginary, and the three fluids cannot rest in contact, the two weaker
**tensions**, even if acting in full concert, being incapable of balancing the strongest. - P. 463) deduced relative to the interfacial
**tensions**of three bodies. - The problem is to make the sum of the interfacial
**tensions**a minimum, each tension being proportional to the square of the difference of densities of the two contiguous liquids in question. - The second minus the first, or the increase in the sum of
**tensions**, is thus 2 (U n - o' n+l) (o n+ 1 - Q n +2) Hence, if an+1 be intermediate in magnitude between a,, and a71+2, the sum of**tensions**is increased by the abolition of the stratum; but, if a-n+1 be not intermediate, the sum is decreased. - We see, then, that the removal of a stratum from between neighbours where it is out of order and its introduction between neighbours where it will be in order is doubly favourable to the reduction of the sum of
**tensions**; and since by a succession of such steps we may arrive at the order of magnitude throughout, we conclude that this is the disposition of minimum**tensions**and energy. - If this takes place more rapidly on one side of the piece of camphor than on the other side, the surface-tension becomes weaker where there is most camphor in solution, and the lump, being pulled unequally by the surface-
**tensions**, moves off in the direction of the strongest tension, namely, towards the side on which least camphor is dissolved. - A comparison under similar circumstances shows that there is hardly any difference in the wave-lengths of the patterns obtained with pure and with soapy water, from which we conclude that at this initial stage, the surface-
**tensions**are the same. - If K is the height of the flat surface of the drop, and k that of the point where its tangent plane is vertical, then T = 1(K - k) 2gp. Quincke finds that for several series of substances the surfacetension is nearly proportional to the density, so that if we call Surface-
**Tensions**of Liquids at their Point of Solidification. - For leather belts on cast-iron pulleys the value of may be taken as o 4, giving a ratio of the
**tensions**on the tight and slack sides of Ti/T2= 3.514, when the angle of wrapping is 180°. - The problem of a rod suspended by strings attached to two points of it is virtually identical, the
**tensions**of the strings taking the place of the reactions of the planes. - When the body is twisted through an angle 0 the threads make angles aC/i, be/I with the vertical, and the moment of the
**tensions**about the vertical through G is accordingly Kg, where K = M gab/i. - F = T1 Ti = T1 (I ef9) Ta(ef 1)j When a belt connecting a pair of pulleys has the
**tensions**of its two sides originally equal, the pulleys being at rest, and when the pulleys are next set in motion, so that one of them drives the other by means of the belt, it is found that the advancing side of the belt is exactly as much tightened as the returning side is slackened, so that the mean tension remains unchanged. - (20) Hence the tension of a thick film is equal to the sum of the
**tensions**of its two surfaces as already calculated (equation 7). - The tension of the surface separating two liquids which do not mix cannot be deduced by any known method from the
**tensions**of the surfaces of the liquids when separately in contact with air. - November 1890) for the
**tensions**of various watersurf aces at 18° C., reckoned in C. G. - When a belt, in which the maximum and minimum
**tensions**are respectively P and p lb, drives a pulley, the torque exerted FIG. - This however, may be due to irregularity of division and displacement of the cells by irregular
**tensions**destroying the obvious layerec arrangement. - The inclined
**tensions**and compressions in the bars of a braced web are equivalent to this shear. **Tensions**between the rich and poor grow higher under the following five circumstances:**Tensions**mounted all through the 1830s as militias were raised on both sides in what later came to be known as the Aroostook War, even though there was never actually a war or casualties.- In the case of high tension voltmeters, the movable plate takes the form of a single plate of paddle shape, and for extra high
**tensions**it may simply be suspended from the end of a balanced arm; or the movable system may take the form of a cylinder which is suspended within, but not touching, another fixed cylinder, the relative position being such that the electric forces draw the suspended cylinder more into the fixed one.
