## Tensions Sentence Examples

- The relation between the three forces acting on any particle, viz, the extraneous force and the
**tensions**in the two adjacent portions of the string can be exhibited by means of a triangle of forces; and if the successive triangles be drawn to the same scale they can be fitted together so as to constitute a single force-diagram, as shown in fig. - These latter lines measure the
**tensions**in the successive portions of string. - We note that the
**tensions**have now the same horizontal projection (represented by the dotted line in fig. - The
**tensions**in the successive portions of the string are therefore proportional to the respective lengths, and thelinesBH,CK.., are all equal. - 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. - 9 is balanced by three determinate
**tensions**(or thrusts) in the three links, provided the directions of the latter are not concurrent. - -- T.r-OT If T, T + aT be the
**tensions**at P, Q, and 4 be the angle between the directions of the curve at these points, the components Q of the**tensions**along the tangent at P give (T + T) cos T, - The weight of PQ and the
**tensions**at P,Q. - In the case of a string stretched over a smooth surface, but in other respects free from extraneous force, the
**tensions**at the ends of a small element s must be balanced by the normal reaction of the surface. - The motion being assumed to be small, the
**tensions**of the two strings may be taken to have their statical values Mgb/(a+b), Mga/(a+b), where a, b are the distances of G from the two threads. - Now that friction is also the difference between the
**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: - 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. - The three angles between the tangent planes to the three surfaces of separation at the point 0 are completely determined by the
**tensions**of the b o a three surfaces. - 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**are equal, and, therefore, they make angles of 120 with each other. - When a drop of one liquid, B, is placed on the surface of another, A, the phenomena which take place depend on the relative magnitude of the three surface-
**tensions**corresponding to the surface between A and air, between B and air, and between A and B. - If no one of these
**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. - This drop will not spread out like the first drop, but will take the form of a flat lens with a distinct circular edge, showing that the surface-tension of what is still apparently pure water is now less than the sum of the
**tensions**of the surfaces separating oil from air and water. - 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. - The resistance to slipping of a flat belt on a pulley may be obtained by considering the equilibrium of a small arc of the pulley surface subtending an angle dB at the centre, and having
**tensions**T and T+dT at its extremities. **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.
