Torsional sentence example
The torsional vibrations of a wire are excited when it is bowed.
If then the torsion head is provided with an index needle, and also if the movable coil is provided with an indicating point, it is possible to measure the torsional angle through which the head must be twisted to bring the movable coil back to its zero position.
In these circumstances the torsional angle becomes a measure of the torque and therefore of the product of the strengths of the currents in the two coils, that is to say, of the square of the strength of the current passing through the two coils if they are joined up in series.
So long as the wire (supposed isotropic) is free from torsional stress, there will be no external evidence of magnetism.
Thus if the magnet is suspended horizontally by a fine wire, which, when the magnetic axis points north and south, is free from torsion, and if 0 is the angle through which the upper end of the wire must be twisted to make the magnet point east and west, then MH = CB, or M = C6/H, where C is the torsional couple for r 0.Advertisement
The velocity of propagation of a torsional disturbance along a wire of circular section may be found by the transfer of momentum method, remembering that we must now replace linear momentum by angular momentum.
When a cart wheel is ungreased it produces a very high note, probably due to torsional vibrations of the axle.
This movement is resisted by the torsional elasticity of the suspending wire, and hence a fixed indicating needle attached to the movable system can be made to indicate directly on a scale, the difference of potential between the terminals of the instrument in volts.
Gripped by a six-piston caliper, braking forces are transferred optimally to the rim, virtually eliminating torsional load on the front wheel.
The high strength tubular steel frame incorporates a closed double cradle for maximum torsional rigidity and strength.Advertisement
The basis of the car is a central, composite monocoque of immense strength and torsional rigidity.
In any case, no torsional oscillations were noticeable during rowing trials.
Hence approximations of the eigenfrequencies for the longitudinal and torsional vibrations can be found immediately.
Frahm,' during an important investigation on the torsional vibration of propeller shafts, measured the relative angular displacement of two flanges on a propeller shaft, selected as far apart as possible, by means of an electrical device (Engineering, 6th of February 1903).
