Question

describe the gyroscopic property of 'precession'

Answer 1

Any spinning object exhibits gyroscopic properties. A

wheel or rotor designed and mounted to utilize these

properties is called a gyroscope. Two important design

characteristics of an instrument gyro are great weight

for its size, or high density, and rotation at high speed

with low friction bearings.

There are two general types of mountings; the type used

depends upon which property of the gyro is utilized. A

freely or universally mounted gyroscope is free to rotate

in any direction about its center of gravity. Such a wheel

is said to have three planes of freedom. The wheel or

rotor is free to rotate in any plane in relation to the base

and is so balanced that with the gyro wheel at rest, it will

remain in the position in which it is placed. Restricted or

semirigidly mounted gyroscopes are those mounted so

that one of the planes of freedom is held fixed in relation

to the base.

There are two fundamental properties of gyroscopic

action—rigidity in space and precession.

Rigidity in space refers to the principle that a gyroscope

remains in a fixed position in the plane in which

it is spinning. By mounting this wheel, or gyroscope,

on a set of gimbal rings, the gyro is able to rotate freely

in any direction. Thus, if the gimbal rings are tilted,

twisted, or otherwise moved, the gyro remains in the

plane in which it was originally spinning.

Precession is the tilting or turning of a gyro in response

to a deflective force. The reaction to this force does not

occur at the point where it was applied; rather, it occurs

at a point that is 90° later in the direction of rotation.

This principle allows the gyro to determine a rate of

turn by sensing the amount of pressure created by

a change in direction. The rate at which the gyro

precesses is inversely proportional to the speed of the

rotor and proportional to the deflective force.

Answer 2

I can answer it.  But you can also look it up on wikipedia.

In short it means "apply torque here, but get a reaction there."

Answer 3

i cant answer this

Answer 4

From Wikipedia  http://en.wikipedia.org/wiki/Precession

Precession refers to a change in the direction of the axis of a rotating object. In physics, there are two types of precession, torque-free and torque-induced, the latter being discussed here in more detail. In certain contexts, "precession" may refer to the precession that the Earth experiences, the effects of this type of precession on astronomical observation, or to the precession of orbital objects.

Answer 5

In a nutshell, it's an apparent wander due to the rotation of the Earth. The gyro wants to stay pointing in the one direction but the Earth rotates around it.

Answer 6

it depends......better try google  

Answer 7

who does he play for.

Answer 8

Gyroscopes are designed to measure angular rate or orientation about a given directional vector. Multi-axis gyros provide measurements in two or three orthogonal directions. There are two basic types of gyroscopes: rate and rate-integrating. Rate gyros are single degree-of-freedom (SDOF) devices with a primarily elastic restraint of the spin axis about the output axis. The output signal is produced by precession of the gimbal, which is proportional to the angular rate of the case about the input axis. Most gyroscopes are rate gyros. Rate-integrating gyros are also SDOF devices, but use a primarily viscous restraint of the spin axis about the output axis. The output signal is produced by precession of the gimbal, but is proportional to the integral of the angular rate of the case about the input axis. Physical specifications for both types of gyroscopes include maximum dimension and weight. Output options include analog voltage, current loop, pulse or frequency, and switch or relay outputs. Gyroscopes that are destined for sale in Europe should comply with Restriction of Hazardous Substances (RoHS), a European Union (EU) directive that requires manufactures to demonstrate that their products contain only minimal levels of hazardous substances.

Selecting gyroscopes requires an understanding of angular rate measurement techniques. Optical gyros permit the reflection of a laser ray many times within an enclosure. If the enclosure rotates, the duration between the moment of laser emittance and eventual reception differs. With ring laser gyros (RLF), the laser reflection is achieved with mirrors inside the enclosure. With fiber optic gyros (FOG), the laser reflection is achieved with a coil of optical fiber. Spinning mass gyros use a steadily-moving mass with a free-moving axis (gimbal). These gyroscopes are very fragile and require regular maintenance. When a spinning mass gyro is titled, the gyroscopic effect causes precession – motion orthogonal to the direction tilt sense – along the axis of the rotating mass, indicating that the angle has moved. Because mechanical constraints cause numerous error factors, the axis of a spinning mass gyro is usually fixed with springs. Spring tension is proportional to the precession speed. Vibrating gyros use micro-electro-mechanical system (MEMS) technology and a vibrating, quartz tuning-fork to measure Coriolis force. When rotated, a vibrating element (vibrating resonator) is subjected to the Coriolis Effect, causing secondary vibration orthogonal to the original vibrating direction. By sensing the secondary vibration, the gyro can detect the rate of turn.

I agree with Boloski!
