# Turn-about Sentence Examples

The varying direction of the inclining couple Pc may be realized by swinging the weight P from a crane on the ship, in a circle of radius c. But if the weight P was lowered on the ship from a crane on shore, the vessel would sink bodily a distance P/wA if P was deposited over F; but deposited anywhere else, say over Q on the water-line area, the ship would

**turn about**a line the antipolar of Q with respect to the confocal ellipse, parallel to FF', at a distance FK from F FK= (k2-hV/A)/FQ sin QFF' (2) through an angle 0 or a slope of one in m, given by P sin B= m wA FK - W'Ak 2V hV FQ sin QFF', (3) where k denotes the radius of gyration about FF' of the water-line area.When the force acts on a body free to

**turn about**a fixed axis only, it is convenient to express the work done by the transformed product TO, where T is the average turning moment or torque acting to produce the displacement 0 radians.If, therefore, the motor is mounted on a cradle free to

**turn about**knife-edges, the reacting torque is the only torque tending to turn the cradle when it is in a vertical position, and may therefore be measured by adjusting weights to hold the cradle in a vertical position.In other words, if the system (considered as rigid) be made to

**turn about**till the first factor coincides with i and the second with j, the product will coincide with k.We note further that if a body be free to

**turn about**a fixed point 0, there are three mutually perpendicular lines through this point about which it can rotate steadily, without further constraint.AdvertisementWe can hence deduce the condition of steady precessional motion in a top. A solid of revolution is supposed to be free to

**turn about**a fixed point 0 on its axis of symmetry, its masscentre G being in this axis at a distance h from 0.If in (21) we imagine that x, y, I denote infinitesimal rotations of a solid free to

**turn about**a fixed point in a given field of force, it appears that the three normal modes consist each of a rotation about one of the three diameters aforesaid, and that the values of in are proportional to the ratios of the lengths of corresponding diameters of the two quadrics.For your first turn,

**turn about**three times and say pussycat backward - then you may begin the quest.Thinking that turn and

**turn about**is fair play, she seized the scissors and cut off one of my curls, and would have cut them all off but for my mother's timely interference.
