Gyroscopes of this type can be extremely accurate and stable. For example, those used in the Gravity Probe B experiment measured changes in gyroscope spin axis orientation to better than 0.5 milliarcseconds (1.4 × 10 −7 degrees, or about 2.4 × 10 −9 radians) over a one-year period. [60]
The result is that the spin vector undergoes precession, just like a classical gyroscope. This phenomenon is known as electron spin resonance (ESR). The equivalent behaviour of protons in atomic nuclei is used in nuclear magnetic resonance (NMR) spectroscopy and imaging.
The torque-free precession rate of an object with an axis of symmetry, such as a disk, spinning about an axis not aligned with that axis of symmetry can be calculated as follows: [1] = where ω p is the precession rate, ω s is the spin rate about the axis of symmetry, I s is the moment of inertia about the axis of symmetry, I p is moment ...
The unusual method of delivery creates a bullet-like spin on the ball with the axis of spin in line with the direction of the throw, similar to the way an American football is thrown. Tezuka has stated, if the pitch is thrown correctly, it will fly straight like a fastball. Contrary to early speculation that the gyroball was a late moving ...
A gyroscope, not to be confused with a gyrocompass, is a spinning wheel mounted on a set of gimbals so that its axis is free to orient itself in any way. [3] When it is spun up to speed with its axis pointing in some direction, due to the law of conservation of angular momentum , such a wheel will normally maintain its original orientation to a ...
While spinning, the flywheel resists any lateral forces acting on it, in a manner similar to a gyroscope. The benefit of this gyroscopic motion is that it counteracts the missile's undesirable tendency to rotate about its central axis, dynamically stabilizing its flight. [ 7 ]
Gyro and shawarma are both meat dishes that are cooked at a very high temperature on a rotating spit — a rod that holds meat in an oven or over an open flame, like a vertical rotisserie — and ...
The spinning electron model here is analogous to a gyroscope. For any rotating body the rate of change of the angular momentum equals the applied torque : = . Note as an example the precession of a gyroscope. The earth's gravitational attraction applies a force or torque to the gyroscope in the vertical direction, and the angular momentum ...
